  • the high affinity of Torin2 for mTOR was proposed, based on a PBKgamma-derived mTOR model, to be due to a pair of hydrogen bonds that are not there in the mTORDn-mLST8- Torin2 structure.
  • the present invention establishes that the high affinity and specificity is due primarily to the extensive stacking of the tricyclic benzonapththyridine ring of Torin2 with the indole group of Trp2239 of mTOR, and secondarily the packing of the Torin2 trifluoromethyl group into the aforementioned N lobe hydrophobic pocket ( Figure 6A).
  • the high affinity and specificity of PP242 for mTOR was not understood, as the paper reporting it noted.
  • the mTORDN-mLST8-PP242 structure showed that the inhibitor causes a conformational change in the inner hydrophobic pocket that is coupled to the binding of the PP242 hydroxyindole group there.

  • D is a moiety that binds to the N-lobe hydrophobic pocket (Ile2163, Pro2169 and Leu2185); in some embodiments, when B and C are both present, the modulator is arranged and constructed such that, when it is bound to mTOR, B and C are arranged in three dimensional space relative to one another on opposite sides of A.

It consists of an N- terminal lobe (N lobe) rich in ⁇ sheet, a larger C-terminal lobe (C lobe), and a cleft in-between the two that binds to ATP. It shares a core structure with PI3K KD fold, but with substantial differences. While the KD structures of the five PI3Ks superimpose on each other essentially across their entire -350 residues, only -250 residues of the mTOR KD align with PI3Ks (FIG. 8).
  • the mTOR KD contains -200 additional residues in unique structural elements that decorate the common fold.

There is also a -40 residue insertion in the C lobe that forms the binding site for mLST8 (residues 2258 to 2296; thereafter LBE).
  • the mTOR KD structure starts prior to the FRB domain, with the long kal helix that is present in PI3Ks as well (FIG. 2A and FIG. 11 A).

This is supported by the 6.6 A x-ray diffraction data of DNAPKcs reported recently 30 . Although the deposited model, which contains a PBK-derived kinase domain, lacks the FRB insertion, a reinterpretation of the data using the mTOR structure reveals strong Fo-Fc electron density indicative of an FRB-like four-helix bundle (FIG. 12B). ATM and ATR appear to lack a comparable insertion.

  • the entire activation loop is well-ordered (FIG. 1 IB), and its middle portion contains the kaAL helix insertion.
  • One side of the activation loop packs with the ka9b insertion, and the other side with the FATC (FIG. 11 A).
  • the FATC is not unique to PIKKs in its entirety, as its N-terminal half forms a helix (kal 1) that is also present in PBK structures 29 ' 32 . Its C- terminal half, which is absent from PBKs, forms three short helices that pack with the activation loop on one side and the LBE on the other (Fig. 2a).
  • FIG. 11 A It partially overlaps with a segment, termed negative regulatory domain (residues).
  • TS mimic 36 reveals that the arrangement of key active site residues is conserved in mTOR (FIG. 2C and FIG. 13C). These include the C lobe Asn2343 and Asp2357, which serve as ligands for the two metal ions, and the N lobe Lys2187, which coordinates the ATP phosphate groups. In addition, Asp2338 superimposes remarkably well with the CDK2 Aspl27, which is a key catalytic residue that helps orient and activate the substrate hydroxyl group for nucleophilic attack 36 ' 37 . The mTOR-CDK2 superposition also reveals a coincidence of the mTOR His2340 and CDK2 Lysl29 side chains (FIG. 2C).
  • FIG. 2D illustrates this with a CDK2 -bound substrate peptide docked by superposing the mTOR and CDK2 TS 36 complexes.

  • the groove In the (+) direction (C-terminal to phosphorylation site), the groove extends only to the +1 position, abruptly terminating with the ka9b helix that plugs this end of the cleft (FIG. 2D). Thereafter, the peptide can exit following the surface of the C lobe towards mLST8, or along the N lobe and towards the FRB.
  • the +1 portion of the groove has a pronounced pocket lined with three aromatic residues, consistent with the two classes of mTOR substrates, exemplified by 4EBP1 and S6K1, having a proline and tyrosine residue, respectively, at +1 (FIG. 15A and FIG. 15B).
  • the groove extends substantially more in the (-) direction, and it may account for the low-level sequence preference at -4 and -5 suggested by a positional scanning peptide array 39 (FIG. 2D).
  • the four-helix bundle FRB substantially extends the N lobe side of the catalytic cleft, running roughly parallel to the C lobe platform and mLST8 on the other side of the cleft. This gives the cleft a deep, "V"-shaped cross-section, restricting access to the substrate-binding site at the bottom of the cleft (FIG. 3A). Substrate access is further hindered by one end of the cleft being plugged by ka9b and the following 55 -residue unstructured segment.
  • deletion that defined the negative regulatory region 33"35 encompasses 7 of 12 ka9b residues and 14 of 55 unstructured-segment residues.
  • deleting the bulk of the unstructured segment does not activate mTOR (FIG. 15), suggesting that ka9b is the key element within the negative regulatory domain.
  • FKBP1224 and mTOR AN -mLST8 structures, FKBP12 extends from the FRB on the N lobe towards mLST8 on the C lobe, nearly capping the catalytic cleft (FIG. 3B). At their closest approach, FKBP12 and mLST8 are only 8 A apart, with the catalytic center recessed by 37 A. The model suggests that rapamycin-FKBP12 inhibits in part by drastically reducing the accessibility of the already constricted catalytic cleft. This is consistent with the extent of mTORCl inhibition being substrate and phosphorylation site dependent 25 .
  • rapamycin-FKBP12 In mTORC2, which is not inhibited by nanomolar rapamycin, there may not be enough space for rapamycin-FKBP12 to access the binding site on the FRB due to the proximity of other mTORC2 components. Consistent with the model that it is the FKBP12 component of rapamycin-FKBP12 that precludes binding to mTORC2, rapamycin can inhibit mTORC2 at micromolar concentrations, when it can bind to the FRB in the absence of FKBP12 Supp 4 .
  • RAPTOR Supp 6 ' Supp 7 as well as a dimeric arrangement of mTORCl Supp'8 , although neither of these effects are observed with yeast TORCl Supp 9 ' Supp l °. It is conceivable that RAPTOR is close enough to the active site that there is barely enough space for FKBP12-rapamycin to fit in. Any residual steric hindrance may destabilize mTOR-RAPTOR during the binding equilibrium of the complex. FRB recruits S6K1 to active site
  • the rapamycin-binding site maps to the FRB surface closest to the active site, in the midst of a hotspot of highly conserved residues (FIG. 4A).
  • Four of these residues are invariant in 22 mTOR orthologs from yeast to man (Ser2035, Phe2039, Trp2102, Phe2108), and another four in 21 (Arg2036, Gln2099, Asp2102, Tyr2105), in stark contrast to the FRB surface opposite from the active site (FIG. 4A and FIG. 16). This raises the possibility that the rapamycin-binding site interacts with substrates to facilitate their entry to the recessed active site.
  • FIG. 4C shows that wild type but not the S2035I FRB mutant 38 ' 40 inhibits overall S6Kl kl phosphorylation by ⁇ 50 % and Thr389 phosphorylation by ⁇ 75 % at the highest concentration tested.
  • Half-maximal inhibition occurs at ⁇ 100-200 ⁇ FRB. This may underestimate the FRB-S6K1 affinity, however, as the isolated FRB-S6K1 association would have to compete with the bivalent binding of both the FRB and active site of mTOR AN to S6Kl .
  • a bi-partite substrate-recruitment mechanism is analogous to what has been proposed for the calcineurin phosphatase, the target of FK506-FKBP12. Most calcineurin substrates require both a primary and a secondary recruitment motif for efficient
  • the secondary motif is rather degenerate, and its calcineurin affinity and importance vary substantially among different substrates 44 , and this too may be analogous in mTOR substrates.

  • a set of buried hydrogen bond contacts at the TRDl-KD interface (between Glul401 and Arg2317) and at the HRD-KD interface (Argl905-Glu2419, and Glnl941Gln2200) involve residues invariant in the 22 mTOR orthologs mentioned above (FIG. 18C).
  • TRDl and HRD segments correspond to the FAT segments best conserved among PIKK family members 28 , suggesting that the FAT domain clamping onto the KD is a common feature of most PIKKs (FIG. 12).
  • PBKs contain a helical repeat domain analogous to the HRD in its structure and interactions with the KD, although they lack the rest of the FAT domain (FIG. 18D).
  • mLST8 consists of seven WD40 repeats. At the narrow end of the mLST8 ⁇ propeller structure, a surface that extends across six WD40 repeats binds to both helices and intervening loop of the helix-loop-helix LBE. The interface involves mostly polar LBE residues and polar/aromatic mLST8 residues, and it is dominated by hydrogen bonds (FIG. 19).
  • mLST8 is thought to be a requisite activating subunit of mTOR complexes 8 ' 9 .
  • the structure suggests that the extended interaction surface of mLST8 may stabilize the helix-loop helix structure of the LBE directly, and the organization of the active site indirectly, through the LBE-FATC-catalytic loop spine of interactions discussed above (FIG. 13 A).
  • lack of mLST8 results in the association of mTOR with heat shock proteins 9 , and we find that the solubility of overexpressed mTOR is highly dependent on mLST8 co-overexpression (not shown).
  • a third cluster of mutations 45 maps to the N-terminal portion of the FAT domain, to structural residues of the TRDl and of the TRDl -proximal portion of TRD2. They likely interfere with the ability of the FAT domain to clamp onto the C lobe of the kinase, with two possible effects.
  • the HRD-KD interactions at the C-terminal end of the FAT solenoid may be indirectly destabilized, as the two FAT ends are structurally, and likely thermodynamically, coupled.
  • the disposition of the N-terminal mTOR segment and its associated RAPTOR which likely further restrict active site access, could change or become more flexible relative to the KD.
  • Inhibitors of the ATP-bindins site [0274] To explore the determinants of inhibitor potency and specificity, we determined the structures of mTOR AN -mLST8 bound to Torin2 and PP242, which are highly specific for mTOR, and to PI-103, which has dual specificity for mTOR and Class I PBKs (FIG. 9).
  • the overall orientation of Torin2 in the mTOR cleft is as predicted 48 (FIG. 6A and FIG. 21 A).
  • the tricyclic benzonapththyridine ring binds to the adenine site and makes a hydrogen bond to the N-C lobe "hinge", analogous to one of two backbone hydrogen bonds made by ATP and diverse PI3/protein kinase inhibitors.
  • the amino-pyridine group reaches into the "inner hydrophobic pocket", an area in the back of the cleft that many kinase inhibitors contact. However, it does not make the three predicted hydrogen bonds (to Asp2195, Asp2357 and Tyr2225) 48 .
  • Trp2239 stacks partially with a three-atom portion of the adenine.
  • Torin2 takes full advantage of Trp2239, with a ten-atom portion of its tricyclic ring stacking with the indole group. This likely makes a substantial contribution to the sub-nanomolar potency 48 of Torin2.
  • Trp2239 is not present in canonical protein kinases or in PBKs, it would also contribute to Torin2's ⁇ 800-fold specificity for mTOR over PBKs 48 .
  • the structure also reveals the packing of the Torin2 trifluoromethyl group packs into an N lobe pocket (Ile2163, Pro2169 and Leu2185; FIG. 6A). These contacts are less extensive than those made to Trp2239, and only Leu2185 is variable across the PIKK and PBK families. However, this portion of the N lobe ⁇ sheet exhibits considerable variation in its relative orientation in PBK structures, and it may thus contribute to Torin2-mTOR specificity.
  • PP242 consists of the adenine -mimetic pyrazolopyrimidine scaffold common to
  • PB/tyrosine kinase inhibitors with a hydroxyindole substituent at a position that often points to the inner hydrophobic pocket 49 .
  • this pocket is lined with residues conserved across the PBK and PIKK families, and the selectivity of PP242 for mTOR was unexpected 49 .
  • the structure reveals that while these two PP242 groups are generally positioned as predicted 49 , mTOR undergoes a conformational change that expands and deepens its inner hydrophobic pocket, with the hydroxyindole group reaching deep into the new space (FIG. 6B and FIG. 2 IB).
  • Leu2354 is replaced by a conserve phenylalanine that cannot undergo a similar conformational change without an even more extensive repacking of the local hydrophobic core. Leu2354 is thus likely to be a major, though indirect, determinant of the selectivity of PP242 for mTOR over PBKs and other kinases.
  • the multi-targeted PI-103 50 does not take advantage of any of the aforementioned mTORspecific features.
  • the morpholine ring binds to the adenine pocket and makes two hydrogen bonds to the "hinge", while the m-phenol group binds to the inner pocket and makes two hydrogen bonds to the Tyr2225 and Asp2195 side chains at the back of the cleft (FIG. 6D and FIG. 21D).
  • These hydrogen bonds are likely to be important for the high affinity of PI-103 for mTOR and, presumably, for Class I PBKs where the relevant protein groups are similarly positioned.
  • the ⁇ 500-fold weaker affinity50 Class III PBK-PI-103 complex lacks both m-phenol hydrogen bonds and one of the "hinge" hydrogen bonds 32 .
  • the mTOR AN structure reveals an intrinsically active but otherwise highly restricted catalytic centre, pointing to substrate recruitment as a major mechanism controlling the kinase activity.
  • Our data indicate that in addition to a primary recruitment motif, a secondary recruitment motif proximal to the substrate phosphorylation site is needed for efficient phosphorylation.

Background
[0002] The mammalian target of rapamycin (mTOR), also known as mechanistic target of rapamycin or FK506 binding protein 12-rapamycin associated protein 1 (FRAPl), is a protein that in humans is encoded by the FRAPl gene (Brown EJ et ah, Nature, 1994 Jun
30;369(6483):756-8; Moore PA et al, Genomics, ) 1996 Apr 15;33(2):331-2). There has been considerable interest in the mTOR signaling pathway because of its role in many processes that have been implicated in both proliferative and metabolic diseases.

(residues 1376 to 2549; thereafter mTORAN) bound to full-length human mLST8, including exemplary data collection, phasing and refinement statistics. mTORAN-mLST8 complex was co- crystallized with ADP, Mg2+ and MgF3 ~, a mimic of the γ-phosphate group of ATP in the transition state (TS)36.

Graph shows quantitation of the 32P autoradiograms (blue circles for mTORAN- mLST8, and red triangles for mTORCl). FIG. 10B depicts exemplary results showing phosphorylation of the indicated concentrations of full-length 4EBP1 by mTORAN-mLST8 and mTORCl . Assays were performed as in FIG. 10A, except for immunob lotting with an antibody specific for 4EBP1 phosphorylated at Thr37 and Thr46.
[0026] Figure 11 depicts exemplary secondary structure, sequence conservation and temperature factors of human mTORAN. FIG. 11A depicts exemplary sequence alignments of human, fish, fly, budding yeast, fission yeast, plant and worm orthologs. Helices are indicated as rounded cylinders, β strands as arrows, segments lacking regular secondary structure as solid lines, and disordered regions as dashed lines. The various domains are colored as in FIG. 1 A. The boundaries between the three TRD and one HRD domains are indicated by arrows.
Segments discussed in text are indicated by horizontal brackets and are labeled. Active site residues are marked by asterisks. The structure-based sequence alignment of the human PIK3C3, a type 3 PI3K (PDB 3IHY), is given as the last sequence extending across the kinase domain. The PIK3C3 residues that superimpose on mTOR are underlined, and dots represent insertions in the mTOR KD relative to PIK3C3. FIG. 11B depicts an exemplary plot of the temperature factors (vertical axis of each panel in A2) of the mTORAN Ca atoms from one of the two mTORAN-mLST8 complexes in the asymmetric unit of the apo crystals. The overall temperature factor of this entire mTORAN protomer is 75.47 A2 (92.60 A2 for the second protomer),and of the kinase domain excluding the FRB is 50.44 A2 (61.37 A2 for the second protomer).
[0027] Figure 12 depicts an exemplary comparison of the mTOR kinase domain to other
PIK s. FIG. 12A depicts an exemplary PIK sequence alignment of the KD region based on the mTOR structure. The FRB-like insertions in SMG1, DNAPKcs and TRRAP are predicted to be alpha helical by the JPRED server (www.compbio.dundee.ac.uk/www-jpred/). ATM and ATR appear to lack an insertion comparable to the FRB. The LBE-like insertions in all six PIKKs are predicted to have two helices, except for the longer insertion in SMG1. Secondary structure restraints from the mTOR structure were included in the alignment with the program Indonesia (xray.bmc.uu.se/dennis/). Annotations as in FIG. 11 A. Residues with over 50 % sequence similarity are indicated in yellow. FIG. 12B is an exemplary model showing an FRB- like domain is present in DNAPKcs. Top panel shows a stereo view of two-fold ncs averaged Fo-Fc electron density for the FRB region using the 6.6 A native data of DNAPKcsSupp 1 and phases from our rebuilding of the deposited model (PDB 3KGV). The deposited model, which lacks helices in the FRB region, is shown in green. Middle panel shows the superimposed mTOR structure, indicating that the FRB-like domain of DNAPKcs is tilted towards the C lobe. Bottom panel shows a manual fitting of the mTOR FRB (red) by optimizing the fit of helices fa land fa2 in the electron density. Helices fa3 and fa4 appear to have different orientations compared to those of mTOR, which is expected given the sequence divergence between the two PIK s.
Figures were prepared with Pymol (The PyMOL Molecular Graphics System, Schrodinger, LLC). Applicants rebuilt the DNAPKcs model by first replacing the PI3K-based kinase domain in the deposited model with that of mTOR using molecular replacement and omitting the FRB, LBE and ka9b to avoid model bias. Inspection of the resulting electron density maps revealed electron density consistent with the presence of all three omitted segments. In addition, the maps indicated that DNAPKcs should have essentially all 28 helices of the mTOR FAT domain, even though the deposited model contained only 17 helices in this region. The mTOR FAT domain was subsequently fitted into electron density that was calculated without any of the FAT helices, first as four rigid bodies corresponding to the TRDl, TRD2, TRD3 and HRD domains, then by adjustment of individual helical repeats (see Fig. 22 for DNAPKcs FAT domain electron density and discussion). The resulting model was used to phase the Fo-Fc electron density shown.
[0028] Figure 13 depicts exemplary results showing the mTOR catalytic residues and reaction mechanism are closely related to canonical protein kinases. FIG. 13A depicts an exemplary stereo view of the spine of interactions (side chains within ~4 A distance) extending from the LBE (magenta) to the FATC (blue), activation loop (A.L. orange) and ka9b (purple) elements in the ATPyS crystals. The catalytic loop (C.L.) is in cyan, and the remaining elements are colored as in FIG. 1 A (light blue for FAT, yellow for N lobe, light pink for C lobe, and green for ATPyS). Purple dotted line indicates disordered loop between ka9b and kalO. FIG. 13B depicts an exemplary stereo view of the Fo-Fc electron density of the ATPyS crystals, calculated at 3.3 A and contoured at 2.5 σ, is shown in blue mesh. Superimposed as red mesh is the anomalous fourier map of apocrystals soaked in AMPPNP and manganese (FIG. 7), after the map was skewed to the unit cell of the ATPyS crystals. FIG. 13C depicts an exemplary structure-based sequence alignment of the catalytic and activation loop portions of mTOR and CDK2 that are superimposed in FIG. 2C, with uppercase CDK2 residues having their Ca atoms within 1.8 A of the corresponding ones in mTOR (lowercase residues are displaced by 2.8 to 4.6 A). The catalytic residues as discussed herein are labeled and in red. Applicants note that the art- proposed mechanism for PI3K postulated that a histidine (corresponding to mTOR His2340) acts as the catalytic base, and an arginine (corresponding to mTOR Arg2339) serves to neutralize the charge of the TS state. However, in mTOR the Arg2339 guanidinium group is -7 A away from γ-phosphate TS mimic, compared to less than -3 A for His2340. Without wishing to be bound by any particular theory, the present invention proposes that mTOR's His2340, rather than Arg2339, acts as the catalytic base. The present disclosure further proposes that, particularly given that the relative arrangement of the Asp2338 catalytic base and the γ-phosphate TS mimic in CDK2 is nearly identical in mTOR, the residue corresponding to mTOR Arg2339 may also act as the catalytic base in other PIK and/or PI3K family kinases. For example, the present invention proposes that Argl27 in CDK2 may act as the catalytic base in this kinase. FIG. 13D depicts exemplary results showing 4EBP1 phosphorylation by wild type, D2338A and H2340A FLAG-mTORAN-mLST8, each at 100 nM concentration. Top panel is an immunoblot using an antibody specific for 4EBP1 phosphorylated at Thr37 and Thr46 and exposed for 15 seconds. Middle panel is the same immunoblot exposed for 180 seconds. Unphosphorylated 4EBP1 (no mTOR added) was run as a background control for the nonspecific signal from the antibody at long exposure times and at 100 μΜ concentration of 4EBP1. From quantitation of multiple exposures the mutations reduce 4EBP1 phosphorylation by a factor of -3000 to -9500. The bottom panel is an immunoblot with an anti-FLAG antibody.
[0029] Figure 14 depicts an exemplary model showing putative substrate -binding grooves on the C lobe portion of the mTOR catalytic cleft. FIG. 14A is an exemplary stick representation of FIG. 2D, showing residues that line the putative substrate-binding groove on the C lobe portion of the catalytic cleft, colored by conservation as in FIG. 2D (+1 position is labeled). In the (+) direction, the groove is lined by Phe2371, Tyr2542 and Trp2545, consistent with a positional scanning peptide array2 showing preference for hydrophobic and aromatic residues at +1. In the (-) direction, there are multiple local pockets that extend farther away from the catalytic center. In addition to hydrophobic residues, there are several polar residues that appear to be uninvolved in stabilizing the structure but are invariant in either all 22 orthologs (His2247) or in all but one (Asn2262 and His2265). Without wishing to be bound by any particular theory, the present disclosure proposes that such pockets could underlie the low-level of sequence preference at the -4 and -5 positions suggested by the positional scanning peptide arraySupp'2. FIG. 14B depicts exemplary sequence alignments of major phosphorylation sites (red asterisk) in the 4EBP1 and AGC kinase substrates of mTOR. Known mTOR substrates appear to lack a strong consensus motif at their phosphorylation sites. The four main
phosphorylation sites of 4EBP1 have essentially no sequence homology flanking the Ser/Thr-Pro sites. While the ~7 residue HM motifs of the S6K1, AKT, PKCa and SGKl AGC family kinases are conserved, they bear little or no relationship to the 4EBP1 sites. In addition, HM motif conservation is due, at least in part, to its role in mediating the activation of the kinase through phosphorylation-induced intra-molecular interactions Supp'3.
[0030] Figure 15 depicts exemplary results of a comparison of the kinase activity of mTORAN-mLST8, full-length mTOR-mLST8, mTOR-mL ST 8 -RAPTOR, and mTORANA2443 ~2486- mLST8 complexes.

Reactions were performed as described in the
Exemplification section herein.
[0031] Figure 16 depicts an exemplary model showing the rapamycin-binding site mapped to the FRB surface closest to the active site, in the midst of a hotspot of highly conserved residues. FIG. 16A depicts an exemplary sequence alignment showing sequence conservation of the FRB in 22 mTOR orthologs and homologs (Tor2 in yeast), with 22/22 identity highlighted in red, and 19/22 in yellow. Residues that make up the conservation hotpsot in and around the rapamycin binding site are marked by asterisks, and are shown in FIG. 16B. FIG. 16B (left panel) depicts an exemplary stick representation of FIG. 4 A, showing the conserved residues in and around the rapamycin binding site. FIG. 16B (right panel) depicts an exemplary isolated FRB (light blue) bound to rapamycin (green) from the FRB-rapamycin- FKBP12 structureSupp U.
[0032] Figure 17 depicts exemplary results illustrating mapping of the S6K1 tail sequences involved in FRB-mediated recruitment to mTOR active site. FIG. 17A depicts exemplary results showing inhibition, by the indicated concentrations of free rapamycin, of mTORAN-mLST8 (100 nM) phosphorylation of full-length S6Klki (blue squares) and a GST- tagged S6K1 polypeptide of residues 351-415 from the C-terminal tail (GST-S6K1351 415, red diamonds), each present at 2 μΜ concentration in the same reaction. Reactions were performed as in the Exemplification section herein. The S6K1 C-terminal tail, which starts with residue 351 immediately after the kinase domain structure Supp' 12 and ends at residue 502, is likely unstructured based on secondary- structure prediction programs (not shown). The reduced 32P incorporation by GST-S6K1351"415 compared to full length S6K1 is due, at least in part, to the presence of multiple in vitro phosphorylation sites after residue 416. FIG. 17B depicts exemplary results showing phosphorylation of the indicated GST-S6K1 tail polypeptides (2 μΜ) by mTORAN-mLST8 (100 nM) and inhibition by free rapamycin (20 μΜ; lanes marked with +). Top panel is the 32P autoradiogram, middle panel immunoblots using an S6K1 phosphoThr389- specific antibody, and bottom is 32P quantitation. Reactions were performed as set forth in the Exemplification section herein. C-terminal truncation of residues 403-410 reduces 32P incorporation ~3-fold, while a further truncation of 399-402 results in an additional ~5-fold reduction, although phosphorylation remains rapamycin-sensitive. While N-terminal truncations of residues 367-381 reduce phosphorylation, this reduction is apparently caused by GST interference, presumably due to its proximity to the HM motif when fused to residue 382, because the reduction is not observed after cleavage of the GST tag (not shown). An alternative explanation for inhibition by free rapamycin and the dominant negative effect of the isolated FRB is that the FRB site mediates dimerization that may be important for substrate phosphorylation. Mammalian but not yeast TORCl can form dimers, although this is dependent on RAPTOR, which is absent in the assays. Nevertheless, Applicant found no evidence of mTORAN-mLST8 dimerization or FRB binding to mTORAN-mLST8. A hypothetical dimer whose inhibition by rapamycin or the isolated FRB would explain reduced S6K1
phosphorylation should be readily detectable, as it would have to form at mTORAN-mLST8 concentrations as low as 20 nM used in the kinase assays of FIG. 4B, C and D.
[0033] Figure 18 depicts an exemplary model showing that FAT forms a C-shaped a solenoid and clamps onto the kinase domain. FIG. 18A depicts an exemplary model illustrating an overall view of the mTORAN-mLST8-ATPYS-Mg complex looking down the vertical axis of FIG. 1, highlighting the C-shaped FAT domain clamping onto the KD. Colored as in FIG. 1. FIG. 18B depicts an exemplary model illustrating an overall view of mTORAN with the FAT domain colored according to its three TPR domains and one HEAT repeat domain. TRDl (light green) has 1.5 repeats, TRD2 (light cyan) has 4.5 repeats, TRD3 (light purple) has 5 repeats, and HRD (light blue) has 3 repeats. Based on the DALI server, TRDl is structurally most similar to TPR repeats of Rab geranylgeranyltransferase-a (1LTX, Z-score 9.1);TRD2 to a synthetic consensus TPR protein (2HYZ; Z-score 13.5); TRD3 to the TPR-containing protein MamA (3ASH; Z-score 12.2), and HRD to the HEAT repeats of the microtubule binding protein XMAP215 (2QK2; Z-score 9.3) and the HEAT repeats of the PI3K pi 10γ (2V4L; Z-score 9.1). The non-canonical TRD1-TRD2 packing involves a lateral shift in the helical arrangement compared to regular TPRs, and it is stabilized by the TRDl a2 packing with the TRD2 l l- l2 loop. The TRD2-TRD3 packing is more divergent, being mediated by the second helix of TRD3 (al4) packing inside the concave surface of TRD2 (a6, a8, alO and al2). This is associated with a reversal of curvature between the two segments, and gives the TRD2-TRD3 portion of the a solenoid a corkscrew-like twist. The HRD C-terminus forms a nearly continuous transition to the kinase N lobe, with only 2 amino acids intervening between the last HRD helix and the first KD helix. FIG. 18C depicts a model showing the interface between TRDl (green) and the KD C lobe (pink). FIG. 18D depicts a model showing the interface between the HRD (light blue) and the KD C lobe (pink) and N lobe (yellow). The red letter "M" indicates two contact residues (Ala2416 and Glu2419) which were isolated as activating mutations of fission yeast Tor2p in the Rheb-independent growth screenSupp'15. FIG. 18E depicts an exemplary model showing the superposition of the three HEAT repeats of the PI3K pi 10a (PDB 2RDO) with the HRD (light blue) of mTOR. The pi 10a HRD domain is in red and the rest of the protein in green. mTOR is colored as in FIG. 18B, except the FRB is in brown. The mTOR HRD-KD contacts are also analogous to the pi 10a HEAT repeat-KD contacts. For example, the mTOR Glnl941-Gln2200 interaction (FIG. 18D) is also present in pi 10a (Gln634-Gln815), and these residues are conserved in all PI3K family members. The rest of the FAT domain N-terminal to the HRD is unrelated to PI3Ks, which typically have at most two helical repeats capping the N-terminus of their HEAT-repeat domain.
[0034] Figure 19 depicts an exemplary model of the mTOR-mLST8 interface. FIG.
19A shows mLST8 (green) consists exclusively of seven WD40 repeats. They fold into a cononical β propeller structure, except for a permutation of the N- and C-terminal strands. The seven blades are numbered lthrough 7, and the strands of each blade are labeled "a" to "d". Whereas in canonical WD40 domains the N-terminal strand corresponds to strand "d" of a blade (blade 7), the N-terminal strand of mLST8 corresponds to strand "b" (blade 1). Only residues 1- 7 and 325-326 of the full-length mLST8 in the crystals are disordered. LBE (residues 2258- 2296) is in pink. FIG. 19B depicts an exemplary model showing the mTOR-mLST8 interface involves all but one of the mLST8 WD40 repeats, and both helices and intervening loop of the LBE, as well as a single residue from the FATC kal2. View is rotated -90° along x from that of FIG. 19A. In the absence of mLST8, there would be only two hydrophobic residues (Met2271 and Met2281) that would be solvent exposed on the LBE. These are unlikely to account for the reduced solubility (not shown) and heat-shock protein association 16 of mTOR overexpressed in the absence of mLST8.
[0035] Figure 20 depicts an exemplary close-up stereo view of activating mutations in the vicinity of ka9b. Activating mutation residues at ka9b or at the structural elements that pack with it (ka3, ka9 and kalO) are shown in red, and the residues in their immediate vicinity are shown in yellow (N lobe), pink (C lobe) or cyan (FAT HRD). Pink dotted line indicates the disordered loop between ka9b and kalO. The hyperactivating mutations were isolated in three separate screens for either bypassing the requirement for Rheb for growthl5, suppressing the temperature-sensitive (ts) growth phenotype of an Lst8ts mutantl7, or resistance to the ATP- competitive inhibitor caffeine. FIG. 5 excludes three mutations that map to screen-specific structural elements. They are the A2290V and L2302Q mutations that map to the LBE and were isolated from the Lst8ts screen (discussed in the mLST8 section of the main text), and the ATP- site W2239R from the caffeine screen. The LBE A2290V and L2302Q mutations have not been assessed biochemically for increased mTOR phosphorylation activity, and the W2239R mutant is unlikely to be a general activating mutation; it has a temperature sensitive phenotype and the structure suggests it would have reduced affinity for both ATP and caffeine. Of the remaining mutations, only a subset has been assessed biochemically. However, the fact that Val2198 mutations were isolated in both the Rheb-null and Lst8ts screens is supportive of the notion that mutations that target the ka9b-centered structural framework have a common effect in increasing mTOR kinase activity. Applicants also note that while one of the mutant alleles from the Lst8ts screen (named SL1) has three mutations, we presume Val2198 is key for the hyperactive phenotype because the other two residues are not evolutionarily conserved.
[0036] Figure 21 depicts an exemplary model of mTOR complexes with Torin2, PP242 and PI- 103. FIG. 21 A shows exemplary modeling of the 3.5 A resolution Fo-Fc electron density of the Torin2-mTORAN-mLST8 crystals, calculated with model phases before the inhibitor was built; density is shown in stereo as a blue mesh contoured at 2.2 σ. View approximately looking down the vertical axis of FIG. 6A. The N lobe portion of the cleft is above the plane of the figure, and it is not shown as it would obstruct the view. Green dotted line indicates atoms that are within hydrogen-bonding distance and geometry. FIG. 21B shows the 3.45 A resolution Fo-Fc electron density of the PP242-mTORAN-mLST8 crystals, calculated as in FIG. 21 A, and contoured at 2.2 σ. FIG. 21C depicts an exemplary omit map of the two polypeptide segments from the N lobe (residues 2223-2226; orange) and C lobe (residues 2353- 2355; pink) of the PP242-mTORAN-mLST8 crystals that undergo a conformational change. The structure of the ATPyS-bound mTOR is in gray, and PP242 in light cyan. The 3.45 A resolution Fo-Fc map was calculated with phases after the model with the omitted segments was subjected to simulated annealing refinement to remove model bias. Contoured at 2.0 σ. FIG. 21D shows the 3.6 A resolution Fo-Fc electron density of the PI-103-mTORAN-mLST8 crystals, calculated as in FIG. 21 A, and contoured at 2.2 σ.
[0037] Figure 22 depicts an exemplary model showing DNAPKcs contains a FAT clamp that interacts with the KD domain as in the mTOR structure. FIG. 22 A depicts an exemplary stereo view of two-fold ncs averaged Fo-Fc electron density for the FAT region using the 6.6 A native data of DNAPKcs 1 and phases from our mTOR-based rebuilding (omitting the FAT) of the deposited model (PDB 3KGV). The deposited model, shown in red, contains only 17 of the 28 main mTOR FAT helices (2/3 helices in TRD1, 6/9 in TRD2, 7/10 in TRD3, and 2/6 in HRD). All but one (a20 of TRD3) of the missing helices are evident at the 2.5 σ contour level shown. FIG. 22B depicts an exemplary stereo view of the DNAPKcs FAT model constructed by fitting the mTOR TRD1, TRD2, TRD3 and HRD domains as rigid bodies into the density (colored as in FIG. 17A). TRDl and HRD require minimal adjustment consistent with their interactions with the KD. TRD2 and TRD3 are shifted and rotated substantially, consistent with their minimal sequence conservation among PIKKs. In addition, individual repeats of TRD2 and TRD3 and the last repeat of the HRD require additional shifts for fitting the electron density (not shown), and they also appear to differ in helix lengths compared to mTOR. FIG. 22C depicts an exemplary mTORAN structure superimposed on the rigid-body domain fitted FAT model of DNAPKcs, underscoring the similar arrangement of TRDl and HRD relative to the KD, but divergent arrangements of TRD2 and TRD3.

[0042] Amino acid: As used herein, the term "amino acid," in its broadest sense, refers to any compound and/or substance that can be incorporated into a polypeptide chain, e.g., through formation of one or more peptide bonds. In some embodiments, an amino acid has the general structure H2N-C(H)(R)-COOH. In some embodiments, an amino acid is a naturally- occurring amino acid. In some embodiments, an amino acid is a synthetic amino acid; in some embodiments, an amino acid is a D-amino acid; in some embodiments, an amino acid is an L- amino acid. "Standard amino acid" refers to any of the twenty standard L-amino acids commonly found in naturally occurring peptides. "Nonstandard amino acid" refers to any amino acid, other than the standard amino acids, regardless of whether it is prepared synthetically or obtained from a natural source. In some embodiments, an amino acid, including a carboxy- and/or amino-terminal amino acid in a polypeptide, can contain a structural modification as compared with the general structure above. For example, in some embodiments, an amino acid may be modified by methylation, amidation, acetylation, and/or substitution as compared with the general structure. In some embodiments, such modification may, for example, alter the circulating half life of a polypeptide containing the modified amino acid as compared with one containing an otherwise identical unmodified amino acid. In some embodiments, such modification does not significantly alter a relevant activity of a polypeptide containing the modified amino acid, as compared with one containing an otherwise identical unmodified amino acid. As will be clear from context, in some embodiments, the term "amino acid" is used to refer to a free amino acid; in some embodiments it is used to refer to an amino acid residue of a polypeptide.
[0043] Animal: As used herein, the term "animal" refers to any member of the animal kingdom. In some embodiments, "animal" refers to humans, at any stage of development. In some embodiments, "animal" refers to non-human animals, at any stage of development. In some embodiments, the non-human animal is a mammal (e.g., a rodent, a mouse, a rat, a rabbit, a monkey, a dog, a cat, a sheep, cattle, a primate, and/or a pig). In some embodiments, animals include, but are not limited to, mammals, birds, reptiles, amphibians, fish, and/or worms. In some embodiments, an animal may be a transgenic animal, genetically-engineered animal, and/or a clone.
[0044] Approximately: As used herein, the term "approximately" and "about" is intended to encompass normal statistical variation as would be understood by those of ordinary skill in the art as appropriate to the relevant context. In certain embodiments, the term
"approximately" or "about" refers to a range of values that fall within 25%, 20%, 19%, 18%, 17%, 16%, 15%, 14%, 13%, 12%, 11%, 10%, 9%, 8%, 7%, 6%, 5%, 4%, 3%, 2%, 1%, or less in either direction (greater than or less than) of the stated reference value unless otherwise stated or otherwise evident from the context (except where such number would exceed 100% of a possible value).
[0045] Associated with: Two events or entities are "associated" with one another, as that term is used herein, if the presence, level and/or form of one is correlated with that of the other. For example, a particular entity (e.g., polypeptide) is considered to be associated with a particular disease, disorder, or condition, if its presence, level and/or form correlates with incidence of and/or susceptibility of the disease, disorder, or condition (e.g., across a relevant population). In some embodiments, two or more entities are physically "associated" with one another if they interact, directly or indirectly, so that they are and remain in physical proximity with one another. In some embodiments, two or more entities that are physically associated with one another are covalently linked to one another; in some embodiments, two or more entities that are physically associated with one another are not covalently linked to one another but are non- covalently associated, for example by means of hydrogen bonds, van der Waals interaction, hydrophobic interactions, magnetism, and combinations thereof.
[0046] Characteristic sequence element: As used herein, the phrase "characteristic sequence element" refers to a sequence element found in a polymer (e.g., in a polypeptide or nucleic acid) that represents a characteristic portion of that polymer. In some embodiments, presence of a characteristic sequence element correlates with presence or level of a particular activity or property of the polymer. In some embodiments, presence (or absence) of a characteristic sequence element defines a particular polymer as a member (or not a member) of a particular family or group of such polymers. A characteristic sequence element typically comprises at least two monomers (e.g., amino acids or nucleotides). In some embodiments, a characteristic sequence element includes at least 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 20, 25, 30, 35, 40, 45, 50, or more monomers (e.g., contiguously linked monomers). In some embodiments, a characteristic sequence element includes at least first and second stretches of continguous monomers spaced apart by one or more spacer regions whose length may or may not vary across polymers that share the sequence element. In certain embodiments, particular characteristic sequence elements may be referred to as "motifs".
[0047] Combination therapy: As used herein, the term "combination therapy" refers to those situations in which a subject is simultaneously exposed to two or more therapeutic agents. In some embodiments, such agents are administered simultaneously; in some embodiments, such agents are administered sequentially; in some embodiments, such agents are administered in overlapping regimens.
[0048] Comparable: The term "comparable", as used herein, refers to two or more agents, entities, situations, sets of conditions, etc that may not be identical to one another but that are sufficiently similar to permit comparison therebetween so that conclusions may reasonably be drawn based on differences or similarities observed. Those of ordinary skill in the art will understand, in context, what degree of identity is required in any given circumstance for two or more such agents, entities, situations, sets of conditions, etc to be considered comparable.
[0049] Computer-readable medium: The term "computer-readable medium", as used herein, refers to non-volatile (i.e. secondary storage) computer data storage and/or memory to retain digital data even when not powered. Examples of computer-readable medium include, but are not limited to hard disk, floppy disk, flash memory(i.e. solid state memory), Ferroelectric RAM (F-RAM), Magnetoresistive RAM (MRAM), optical disc, standalone RAM disks, ZIP drives, magenetic tape and holographic memory.
[0050] Computer system: The term "computer system" or "computer", as used herein, refers to a computing device that can be used to implement the techniques described in this disclosure. An exemplary computing device 2500 and a mobile computing device are shown in FIG. 24.
[0051] Corresponding to: As used herein, the term "corresponding to" is often used to designate the position/identity of a residue in a polymer, such as an amino acid residue in a polypeptide or a nucleotide residue in a nucleic acid. Those of ordinary skill will appreciate that, for purposes of simplicity, residues in such a polymer are often designated using a canonical numbering system based on a reference related polymer, so that a residue in a first polymer "corresponding to" a residue at position 190 in the reference polymer, for example, need not actually be the 190th residue in the first polymer but rather corresponds to the residue found at the 190th position in the reference polymer; those of ordinary skill in the art readily appreciate how to identify "corresponding" amino acids, including through use of one or more
commercially-available algorithms specifically designed for polymer sequence comparisons.
[0052] Crystal structure: As used herein, the term "crystal structure" of a composition shall mean a computer readable medium in which is stored a representation of three dimensional positional information (i.e. coordinates) for atoms of the composition. [0053] Derivative: As used herein, the term "derivative" refers to a structural analogue of a reference substance. That is, a "derivative" is a substance that shows significant structural similarity with the reference substance, for example sharing a core or consensus structure, but also differs in certain discrete ways. In some embodiments, a derivative is a substance that can be generated from the reference substance by chemical manipulation. In some embodiemnts, a derivative is a substance that can be generated through performance of a synthetic process substantially similar to (e.g., sharing a plurality of steps with) one that generates the reference substance.
[0054] Docking: As used herein, the term "docking" refers to orienting, rotating, translating a chemical entity in the binding pocket, domain, molecule or molecular complex or portion thereof based on distance geometry or energy. Docking may be performed by distance geometry methods that find sets of atoms of a chemical entity that match sets of sphere centers of the binding pocket, domain, molecule or molecular complex or portion thereof. See Meng et al. J. Comp. Chem. 4: 505-524 (1992). Sphere centers are generated by providing an extra radius of given length from the atoms (excluding hydrogen atoms) in the binding pocket, domain, molecule or molecular complex or portion thereof. Real-time interaction energy calculations, energy minimizations or rigid-body minimizations (Gschwend et al., J. Mol. Recognition 9: 175- 186 (1996)) can be performed while orienting the chemical entity to facilitate docking. For example, interactive docking experiments can be designed to follow the path of least resistance. If the user in an interactive docking experiment makes a move to increase the energy, the system will resist that move. However, if that user makes a move to decrease energy, the system will favor that move by increased responsiveness. (Cohen et al, J. Med. Chem. 33:889-894 (1990)). Docking can also be performed by combining a Monte Carlo search technique with rapid energy evaluation using molecular affinity potentials. See Goodsell and Olson, Proteins: Structure, Function and Genetics 8:195-202 (1990). Software programs that carry out docking functions include but are not limited to MATCHMOL (Cory et al, J. Mol. Graphics 2: 39 (1984);
MOLFIT (Redington, Comput. Chem. 16: 217 (1992)) and DOCK (Meng et al, supra). [0055] Dosage form: As used herein, the term "dosage form" refers to a physically discrete unit of a therapeutic agentfor administration to a subject. Each unit contains a predetermined quantity of active agent. In some embodiments, such quantity is a unit dosage amount (or a whole fraction thereof) appropriate for administration in accordance with a dosing regimen that has been determined to correlate with a desired or beneficial outcome when administered to a relevant population (i.e., with a therapeutic dosing regimen).
[0056] Designed: As used herein, the term "designed" refers to an agent (i) whose structure is or was selected by the hand of man; (ii) that is produced by a process requiring the hand of man; and/or (iii) that is distinct from natural substances and other known agents.
[0057] Dosing regimen: As used herein, the term "dosing regimen" refers to a set of unit doses (typically more than one) that are administered individually to a subject, typically separated by periods of time. In some embodiments, a given therapeutic agent has a
recommended dosing regimen, which may involve one or more doses. In some embodiments, a dosing regimen comprises a plurality of doses each of which are separated from one another by a time period of the same length; in some embodiments, a dosing regimen comprises a plurality of doses and at least two different time periods separating individual doses. In some embodiments, a dosing regimen is correlated with a desired or beneficial outcome when administered across a relevant population (i.e., is a therapeutic dosing regimen).
[0058] Engineered: In general, the term "engineered" refers to the aspect of having been manipulated by the hand of man. For example, a polynucleotide is considered to be
"engineered" when two or more sequences, that are not linked together in that order in nature, are manipulated by the hand of man to be directly linked to one another in the engineered polynucleotide. For example, in some embodiments of the present invention, an engineered polynucleotide comprises a regulatory sequence that is found in nature in operative association with a first coding sequence but not in operative association with a second coding sequence, is linked by the hand of man so that it is operatively associated with the second coding sequence. Comparably, a cell or organism is considered to be "engineered" if it has been manipulated so that its genetic information is altered {e.g., new genetic material not previously present has been introduced, for example by transformation, mating, somatic hybridization, transfection, transduction, or other mechanism, or previously present genetic material is altered or removed, for example by substitution or deletion mutation, or by mating protocols). As is common practice and is understood by those in the art, progeny of an engineered polynucleotide or cell are typically still referred to as "engineered" even though the actual manipulation was performed on a prior entity.
[0059] Fragment: A "fragment" of a material or entity as described herein has a structure that includes a discrete portion of the whole, but lacks one or more moieties found in the whole. In some embodiments, a fragment consists of such a discrete portion. In some embodiments, a fragment consists of or comprises a characteristic structural element or moiety found in the whole. In some embodiments, a polymer fragment comprises or consists of at least 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100, 110, 120, 130, 140, 150, 160, 170, 180, 190, 200, 210, 220, 230, 240, 250, 275, 300, 325, 350, 375, 400, 425, 450, 475, 500 or more monomeric units (e.g., residues) as found in the whole polymer. In some embodiments, a polymer fragment comprises or consists of at least about 5%, 10%, 15%, 20%, 25%, 30%, 25%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, 96%, 97%, 98%, 99% or more of the monomeric units (e.g., residues) found in the whole polymer. The whole material or entity may in some embodiments be referred to as the "parent" of the whole.
[0060] Homology: As used herein, the term "homology" refers to the overall relatedness between polymeric molecules, e.g., between nucleic acid molecules {e.g., DNA molecules and/or RNA molecules) and/or between polypeptide molecules. In some embodiments, polymeric molecules are considered to be "homologous" to one another if their sequences are at least 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, or 99% identical. In some embodiments, polymeric molecules are considered to be "homologous" to one another if their sequences are at least 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%), 80%), 85%o, 90%), 95%, or 99% similar (e.g., containing residues with related chemical properties at corresponding positions). For example, as is well known by those of ordinary skill in the art, certain amino acids are typically classified as similar to one another as "hydrophobic" or "hydrophilic"amino acids, and/or as having "polar" or "non-polar" side chains. Substitution of one amino acid for another of the same type may often be considered a "homologous" substitution. Typical amino acid categorizations are summarized below:

Tyrosine Tyr Y polar neutral -1.3
Valine Val V nonpolar neutral 4.2
Figure imgf000028_0001
[0061] As will be understood by those skilled in the art, a variety of algorithms are available that permit comparison of sequences in order to determine their degree of homology, including by permitting gaps of designated length in one sequence relative to another when considering which residues "correspond" to one another in different sequences. Calculation of the percent homology between two nucleic acid sequences, for example, can be performed by aligning the two sequences for optimal comparison purposes (e.g., gaps can be introduced in one or both of a first and a second nucleic acid sequences for optimal alignment and non- corresponding sequences can be disregarded for comparison purposes). In certain embodiments, the length of a sequence aligned for comparison purposes is at least 30%, at least 40%, at least 50%, at least 60%, at least 70%, at least 80%, at least 90%, at least 95%, or substantially 100% of the length of the reference sequence. The nucleotides at corresponding nucleotide positions are then compared. When a position in the first sequence is occupied by the same nucleotide as the corresponding position in the second sequence, then the molecules are identical at that position; when a position in the first sequence is occupied by a similar nucleotide as the corresponding position in the second sequence, then the molecules are similar at that position. The percent homology between the two sequences is a function of the number of identical and similar positions shared by the sequences, taking into account the number of gaps, and the length of each gap, which needs to be introduced for optimal alignment of the two sequences. Representative algorithms and computer programs useful in determining the percent homology between two nucleotide sequences include, for example, the algorithm of Meyers and Miller (CABIOS, 1989, 4: 11-17), which has been incorporated into the ALIGN program (version 2.0) using a PAM120 weight residue table, a gap length penalty of 12 and a gap penalty of 4. The percent homology between two nucleotide sequences can, alternatively, be determined for example using the GAP program in the GCG software package using an NWSgapdna.CMP matrix.
[0062] Homology model: As used herein, the term "homology model" refers to a set of coordinates derived from known three-dimensional structure used as template. Generation of the homology model, termed "homology modeling", involves sequence alignment, residue replacement and residue conformation adjustment through energy minimization.
[0063] Human: In some embodiments, a human is an embryo, a fetus, an infant, a child, a teenager, an adult, or a senior citizen.
[0064] Hydrophilic: As used herein, the term "hydrophilic" and/or "polar" refers to a tendency to mix with, or dissolve easily in, water.
[0065] Hydrophobic: As used herein, the term "hydrophobic" and/or "non-polar", refers to a tendency to repel, not combine with, or an inability to dissolve easily in, water.
[0066] Identity: As used herein, the term "identity" refers to the overall relatedness between polymeric molecules, e.g., between nucleic acid molecules (e.g., DNA molecules and/or RNA molecules) and/or between polypeptide molecules. In some embodiments, polymeric molecules are considered to be "substantially identical" to one another if their sequences are at least 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, or 99% identical. As will be understood by those skilled in the art, a variety of algorithms are available that permit comparison of sequences in order to determine their degree of homology, including by permitting gaps of designated length in one sequence relative to another when considering which residues "correspond" to one another in different sequences. Calculation of the percent identity between two nucleic acid sequences, for example, can be performed by aligning the two sequences for optimal comparison purposes (e.g., gaps can be introduced in one or both of a first and a second nucleic acid sequences for optimal alignment and non- corresponding sequences can be disregarded for comparison purposes). In certain embodiments, the length of a sequence aligned for comparison purposes is at least 30%, at least 40%, at least 50%, at least 60%, at least 70%, at least 80%, at least 90%, at least 95%, or substantially 100% of the length of the reference sequence. The nucleotides at corresponding nucleotide positions are then compared. When a position in the first sequence is occupied by the same nucleotide as the corresponding position in the second sequence, then the molecules are identical at that position. The percent identity between the two sequences is a function of the number of identical positions shared by the sequences, taking into account the number of gaps, and the length of each gap, which needs to be introduced for optimal alignment of the two sequences. Representative algorithms and computer programs useful in determinng the percent identity between two nucleotide sequences include, for example, the algorithm of Meyers and Miller (CABIOS, 1989, 4: 11-17), which has been incorporated into the ALIGN program (version 2.0) using a PAM120 weight residue table, a gap length penalty of 12 and a gap penalty of 4. The percent identity between two nucleotide sequences can, alternatively, be determined for example using the GAP program in the GCG software package using an NWSgapdna.CMP matrix.
[0067] Inhibition model: As used herein, the term "inhibition model" refers to a region or regions of proteins that can associate with another chemical entity or compound. Such regions are of significant utility in fields such as drug discovery. These regions are formed by amino acid residues key for ligand binding or may be residues that are spatially related and define a three-dimensional shape of the binding pocket. In some embodiments, the amino acid residues may be contiguous or non-contiguous in primary sequence. In some embodiments, the region or regions may be embodied as a dataset (e.g. an array of structure coordinates) recorded on computer readable media.
[0068] Isolated: As used herein, the term "isolated" refers to a substance and/or entity that has been (1) separated from at least some of the components with which it was associated when initially produced (whether in nature and/or in an experimental setting), and/or (2) designed, produced, prepared, and/or manufactured by the hand of man. Isolated substances and/or entities may be separated from about 10%, about 20%, about 30%>, about 40%>, about 50%, about 60%, about 70%, about 80%, about 90%, about 91%, about ,%, about 93%, about 94%, about 95%, about 96%, about 97%, about 98%, about 99%, or more than about 99% of the other components with which they were initially associated. In some embodiments, isolated agents are about 80%, about 85%, about 90%, about 91%, about 92%, about 93%, about 94%, about 95%, about 96%, about 97%, about 98%, about 99%, or more than about 99% pure. As used herein, a substance is "pure" if it is substantially free of other components. In some embodiments, as will be understood by those skilled in the art, a substance may still be considered "isolated" or even "pure", after having been combined with certain other components such as, for example, one or more carriers or excipients (e.g., buffer, solvent, water, etc.); in such embodiments, percent isolation or purity of the substance is calculated without including such carriers or excipients. In some embodiments, isolation involves or requires disruption of covalent bonds (e.g., to isolate a polypeptide domain from a longer polypeptide and/or to isolate a nucleotide sequence element from a longer oligonucleotide or nucleic acid).
[0069] Modulator: The term "modulator" is used to refer to an entity whose presence in a system in which an activity of interest is observed correlates with a change in level and/or nature of that activity as compared with that observed under otherwise comparable conditions when the modulator is absent. In some embodiments, a modulator is an activator, in that activity is increased in its presence as compared with that observed under otherwise comparable conditions when the modulator is absent. In some embodiments, a modulator is an inhibitor, in that activity is reduced in its presence as compared with otherwise comparable conditions when the modulator is absent. In some embodiments, a modulator interacts directly with a target entity whose activity is of interest. In some embodiments, a modulator interacts indirectly (i.e., directly with an intermediate agent that interacts with the target entity) with a target entity whose activity is of interest. In some embodiments, a modulator affects level of a target entity of interest; alternatively or additionally, in some embodiments, a modulator affects activity of a target entity of interest without affecting level of the target entity. In some embodiments, a modulator affects both level and activity of a target entity of interest, so that an observed difference in activity is not entirely explained by or commensurate with an observed difference in level.
[0070] Nucleic acid: As used herein, the term "nucleic acid," in its broadest sense, refers to any compound and/or substance that is or can be incorporated into an oligonucleotide chain. In some embodiments, a nucleic acid is a compound and/or substance that is or can be incorporated into an oligonucleotide chain via a phosphodiester linkage. As will be clear from context, in some embodiments, "nucleic acid" refers to individual nucleic acid residues {e.g., nucleotides and/or nucleosides); in some embodiments, "nucleic acid" refers to an
oligonucleotide chain comprising individual nucleic acid residues. In some embodiments, a "nucleic acid" is or comprises R A; in some embodiments, a "nucleic acid" is or comprises DNA. In some embodiments, a nucleic acid is, comprises, or consists of one or more natural nucleic acid residues. In some embodiments, a nucleic acid is, comprises, or consists of one or more nucleic acid analogs. In some embodiments, a nuclic acid analog differs from a nucleic acid in that it does not utilize a phosphodiester backbone. For example, in some embodiments, a nucleic acid is, comprises, or consists of one or more "peptide nucleic acids", which are known in the art and have peptide bonds instead of phosphodiester bonds in the backbone, are considered within the scope of the present invention. Alternatively or additionally, in some embodiments, a nucleic acid has one or more phosphorothioate and/or 5'-N-phosphoramidite linkages rather than phosphodiester bonds. In some embodiments, a nucleic acid is, comprises, or consists of one or more natural nucleosides (e.g., adenosine, thymidine, guanosine, cytidine, uridine, deoxyadenosine, deoxythymidine, deoxyguanosine, and deoxy cytidine).

In some embodiments, a nucleic acid comprises one or more modified sugars (e.g., 2'-fluororibose, ribose, 2'-deoxyribose, arabinose, and hexose) as compared with those in natural nucleic acids. In some embodiments, a nucleic acid has a nucleotide sequence that encodes a functional gene product such as an RNA or protein. In some embodiments, a nucleic acid includes one or more introns. In some embodiments, nucleic acids are prepared by one or more of isolation from a natural source, enzymatic synthesis by polymerization based on a complementary template (in vivo or in vitro), reproduction in a recombinant cell or system, and chemical synthesis. In some embodiments, a nucleic acid is at least 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100, 110, 120, 130, 140, 150, 160, 170, 180, 190, 20, 225, 250, 275, 300, 325, 350, 375, 400, 425, 450, 475, 500, 600, 700, 800, 900, 1000, 1500, 2000, 2500, 3000, 3500, 4000, 4500, 5000 or more residues long.

[0073] Polypeptide: The term "polypeptide", as used herein, generally has its art- recognized meaning of a polymer of at least three amino acids, linked to one another by peptide bonds. In some embodiments, the term is used to refer to specific functional classes of polypeptides, such as, for example, autoantigen polypeptides, nicotinic acetylcholine receptor polypeptides, alloantigen polypeptides, etc. For each such class, the present specification provides several examples of amino acid sequences of known exemplary polypeptides within the class; in some embodiments, such known polypeptides are reference polypeptides for the class. In such embodiments, the term "polypeptide" refers to any member of the class that shows significant sequence homology or identity with a relevant reference polypeptide. In many embodiments, such member also shares significant activity with the reference polypeptide. For example, in some embodiments, a member polypeptide shows an overall degree of sequence homology or identity with a reference polypeptide that is at least about 30-40%, and is often greater than about 50%, 60%, 70%, 80%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or more and/or includes at least one region (i.e., a conserved region, often including a characteristic sequence element) that shows very high sequence identity, often greater than 90% or even 95%, 96%, 97%, 98%, or 99%. Such a conserved region usually encompasses at least 3- 4 and often up to 20 or more amino acids; in some embodiments, a conserved region
encompasses at least one stretch of at least 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 or more contiguous amino acids.

[0074] Protein: As used herein, the term "protein" refers to a polypeptide {i.e., a string of at least two amino acids linked to one another by peptide bonds). Proteins may include moieties other than amino acids {e.g., may be glycoproteins, proteoglycans, etc.) and/or may be otherwise processed or modified. Those of ordinary skill in the art will appreciate that a "protein" can be a complete polypeptide chain as produced by a cell (with or without a signal sequence), or can be a characteristic portion thereof. Those of ordinary skill will appreciate that a protein can sometimes include more than one polypeptide chain, for example linked by one or more disulfide bonds or associated by other means. Polypeptides may contain L-amino acids, D- amino acids, or both and may contain any of a variety of amino acid modifications or analogs known in the art. Useful modifications include, e.g., terminal acetylation, amidation,

The term "peptide" is generally used to refer to a polypeptide having a length of less than about 100 amino acids, less than about 50 amino acids, less than 20 amino acids, or less than 10 amino acids. In some embodiments, proteins are antibodies, antibody fragments, biologically active portions thereof, and/or characteristic portions thereof.
[0075] Reference: The term "reference" is often used herein to describe a standard or control agent or value against which an agent or value of interest is compared. In some embodiments, a reference agent is tested and/or a reference value is determined substantially simultaneously with the testing or determination of the agent or value of interest. In some embodiments, a reference agent or value is a historical reference, optionally embodied in a tangible medium. Typically, as would be understood by those skilled in the art, a reference agent or value is determined or characterized under conditions comparable to those utilized to determine or characterize the agent or value of interest.
[0076] Small molecule: As used herein, the term "small molecule" means a low molecular weight organic compound that may serve as an enzyme substrate or regulator of biological processes. In general, a "small molecule" is a molecule that is less than about 5 kilodaltons (kD) in size. In some embodiments, provided nanoparticles further include one or more small molecules. In some embodiments, the small molecule is less than about 4 kD, 3 kD, about 2 kD, or about 1 kD. In some embodiments, the small molecule is less than about 800 daltons (D), about 600 D, about 500 D, about 400 D, about 300 D, about 200 D, or about 100 D.

In some embodiments, a small molecule is an adjuvant. In some embodiments, a small molecule is a drug.
[0077] Storage environment: As used herein, the term "storage environment" comprises any environment comprising secondary storage, i.e. long-term persistent storage. In some embodiments, a storage environment comprises computer-readable medium. In some embodiments, a storage environment comprises a network environment for establishing a multichannel context aware communication environment (i.e. cloud computing). For example, FIG. 25 is a block diagram of a network environment for establishing a multi-channel context aware communication environment.
[0078] Subject: As used herein, the term "subject" refers to a human or any non-human animal (e.g., mouse, rat, rabbit, dog, cat, cattle, swine, sheep, horse or primate). A human includes pre and post natal forms. In many embodiments, a subject is a human being. A subject can be a patient, which refers to a human presenting to a medical provider for diagnosis or treatment of a disease. A subject can be afflicted with or is susceptible to a disease or disorder but may or may not display symptoms of the disease or disorder.
[0079] Substantially: As used herein, the term "substantially" refers to the qualitative condition of exhibiting total or near-total extent or degree of a characteristic or property of interest. One of ordinary skill in the biological arts will understand that biological and chemical phenomena rarely, if ever, go to completion and/or proceed to completeness or achieve or avoid an absolute result. The term "substantially" is therefore used herein to capture the potential lack of completeness inherent in many biological and chemical phenomena.
[0080] Suffering from: An individual who is "suffering from" a disease, disorder, or condition has been diagnosed with and/or exhibits or has exhibited one or more symptoms or characteristics of the disease, disorder, or condition. [0081] Susceptible to: An individual who is "susceptible to" a disease, disorder, or condition is at risk for developing the disease, disorder, or condition. In some embodiments, an individual who is susceptible to a disease, disorder, or condition does not display any symptoms of the disease, disorder, or condition. In some embodiments, an individual who is susceptible to a disease, disorder, or condition has not been diagnosed with the disease, disorder, and/or condition. In some embodiments, an individual who is susceptible to a disease, disorder, or condition is an individual who has been exposed to conditions associated with development of the disease, disorder, or condition. In some embodiments, a risk of developing a disease, disorder, and/or condition is a population-based risk {e.g., family members of individuals suffering from allergy, etc.
[0082] Symptoms are reduced: According to the present invention, "symptoms are reduced" when one or more symptoms of a particular disease, disorder or condition is reduced in magnitude {e.g., intensity, severity, etc.) and/or frequency. For purposes of clarity, a delay in the onset of a particular symptom is considered one form of reducing the frequency of that symptom.
[0083] Therapeutic agent: As used herein, the phrase "therapeutic agent" refers to any agent that has a therapeutic effect and/or elicits a desired biological and/or pharmacological effect, when administered to a subject. In some embodiments, an agent is considered to be a therapeutic agent if its administration to a relevant population is statistically correlated with a desired or beneficial therapeutic outcome in the population, whether or not a particular subject to whom the agent is administered experiences the desired or beneficial therapeutic outcome.
[0084] Therapeutically effective amount: As used herein, the term "therapeutically effective amount" means an amount that is sufficient, when administered to a population suffering from or susceptible to a disease, disorder, and/or condition in accordance with a therapeutic dosing regimen, to treat the disease, disorder, and/or condition {e.g., allergy). In some embodiments, a therapeutically effective amount is one that reduces the incidence and/or severity of, and/or delays onset of, one or more symptoms of the disease, disorder, and/or condition. Those of ordinary skill in the art will appreciate that the term "therapeutically effective amount" does not in fact require successful treatment be achieved in a particular individual. Rather, a therapeutically effective amount may be that amount that provides a particular desired pharmacological response in a significant number of subjects when
administered to patients in need of such treatment. It is specifically understood that particular subjects may, in fact, be "refractory" to a "therapeutically effective amount." To give but one example, a refractory subject may have a low bioavailability such that clinical efficacy is not obtainable. In some embodiments, reference to a therapeutically effective amount may be a reference to an amount as measured in one or more specific tissues (e.g., a tissue affected by the disease, disorder or condition) or fluids (e.g., blood, saliva, serum, sweart, tears, urine, etc). Those of ordinary skill in the art will appreciate that, in some embodiments, a therapeutically effective agent may be formulated and/or administered in a single dose. In some embodiments, a therapeutically effective agent may be formulated and/or administered in a plurality of doses, for example, as part of a dosing regimen.
[0085] Therapeutic regimen: A "therapeutic regimen", as that term is used herein, refers to a dosing regimen whose administration across a relevant population is correlated with a desired or beneficial therapeutic outcome.
[0086] Treatment: As used herein, the term "treatment" (also "treat" or "treating") refers to any administration of a substance that partially or completely alleviates, ameliorates, relives, inhibits, delays onset of, reduces severity of, and/or reduces frequency, incidence or severity of one or more symptoms, features, and/or causes of a particular disease, disorder, and/or condition. Such treatment may be of a subject who does not exhibit signs of the relevant disease, disorder and/or condition and/or of a subject who exhibits only early signs of the disease, disorder, and/or condition. Alternatively or additionally, such treatment may be of a subject who exhibits one or more established signs of the relevant disease, disorder and/or condition. In some embodiments, treatment may be of a subject who has been diagnosed as suffering from the relevant disease, disorder, and/or condition. In some embodiments, treatment may be of a subject known to have one or more susceptibility factors that are statistically correlated with increased risk of development of the relevant disease, disorder, and/or condition. [0087] Three dimensional representation: As used herein, the term " three dimensional representation" refers to converting the lists of structure coordinates into structural models or graphical representation in three-dimensional space. In some embodiments, the three
dimensional structure may be displayed or used to performing computer modeling or fitting operations. In some embodiments, the structure coordinates themselves, without the displayed model, may be used to perform computer-based modeling and fitting operations.
Detailed Description of Certain Embodiments
mTor
[0088] The mTOR pathway controls cell growth in response to energy, nutrients, growth factors and other environmental cues, and it figures prominently in cancer1'2. Central to the pathway is the mammalian target of rapamycin (mTOR) protein that belongs to the
phosphoinositide 3-kinase (PI3K)-related protein kinase (PIK ) family3.
[0089] mTOR assembles into two different complexes within cells with distinct inputs and downstream effects. mTOR Complex 1 (mTORCl) is defined by its RAPTOR subunit4"6, which is replaced by RICTOR in mTORC26'7. Both complexes also contain the requisite mLST8 subunit8'9, but they differ in a number of other subunits that interact with RAPTOR or RICTORl .
[0090] mTORCl regulates cell growth by promoting translation, ribosome biogenesis and autophagy1'4'5. Its activation requires nutrients and amino acids, which result in the
RAPTOR-mediated recruitment of mTORCl to lysosomes and late endosomes10'11, and co- localization with its activator, the small GTPase RHEB12'13. Proposed mechanisms of RHEB action include binding to and activating the mTOR kinase domain14, and the displacement of the mTORCl inhibitor PRAS40 from RAPTOR15'16. RHEB in turn is negatively-regulated by the GTPase-activating domain of the TSC2 tumor suppressor, which relays signals from multiple growth factor and stress pathways17. mTORCl substrates include the eIF4E-binding protein 1 (4EBP1) and ribosomal S6 kinases (S6K), which control cap-dependent translation initiation and elongation, respectively18. Phosphorylation of 4EBP1 and S6K1 is dependent on their Tor Signaling Sequence (TOS) motif ' that binds to RAPTOR, and which is also present in the negative regulator PRAS4021'22. Table 7 presents representative sequences produced by engineered expression constructs for certain such associated mTOR proteins:
Table 7: Representative sequences produced by engineered expression constructs
Figure imgf000040_0001
[0091] mTORC2 responds primarily to growth factors, promoting cell-cycle entry, cell survival, actin cytoskeleton polarization, and anabolic output6'7'23. Its substrates include the Ser/Thr protein kinases AKT, SGK and PKC, which share the hydrophobic motif (HM) phosphorylation site with S6K11,2 .
mTOR Structure
[0092] mTOR has a characteristic multidomain structure comprising a kinase domain,
FRB (FKBP12-Rapamycin Binding) domain, a putative auto-inhibitory domain (Repressor domain) near the C-terminus and up to 20 tandemly repeated HEAT motifs at the amino terminus, as well as FAT (FRAP-ATM-TRRAP) and FATC (FAT C-terminus) domains. mTOR proteins have been identified in a variety of species, and have been sequenced. Table 8 presents exemplary sequences of certain such mTOR proteins:
Table 8: Exemplary mTOR and related sequences
Figure imgf000041_0001
(chimpanzee) JAA36279
[0093] Figures 11 A, 12A and 23 present or include various sequence alignments illustrating conservation of certain sequence elements within mTOR proteins.
[0094] As can be seen, and as is known by those of ordinary skill in the art, various conserved sequence elements are found within mTOR protein domains, and in certain embodiments can be considered to be "characteristic" of mTOR polypeptides. For example, Table 9 presents certain representative sequence elements that may be found in exemplary mTOR polypeptides.
Table 9: Re resentative sequences characteristic of mTOR polypetpides

[0095] As discussed herein, mTOR is generally considered to be a member of the PIK kinase family, which is related to the PI3K kinase family. Figure 12 shows sequence alignments of certain mTOR polypeptides with one another and with certain mammalian PIK s. The six mammalian PIKKs regulate diverse cellular processes27. They share three regions of homology consisting of a -600 residue FAT domain (FRAP, ATM, TRRAP), a -300 residue PI3K-related protein kinase catalytic domain, and a ~35 residue FATC domain at the Cterminus28. In mTOR, the art-accepted location of the -100 residue FRB domain was thought to occur in-between the FAT and catalytic domains (i.e. the structure proposed and accepted in the art prior to the present disclosure has the FRB domain occurring prior to the kinase domain), and the region N-terminal to the FAT domain is required for binding to RAPTOR and RICTORl . One aspect of the present invention is the surprising and unexpected result that, contrary to the art-proposed structure, the FRB occurs within the kinase domain.
[0096] In general, PI3K proteins also typically include kinase, ATP-binding, and catalytic loop and activation loop motifs. Table 10 includes various sequences found in PI3K and/or PIKK proteins.

[0101] Alternatively or additionally, in some embodiments, an mTOR polypeptide is one that shares an overall level of sequence identitiy and/or one or more characteristic sequence elements with a reference PI3K or PIKK protein (e.g., as set forth in Table 1 1), or a
corresponding fragment thereof. In some embodiments, an mTOR polypeptide shares an overall degree s as described herein are shared between the mTOR polypeptide and one or more PI3K and/or PIKK kinases. In some embodiments, an mTOR polypeptide of interest is one that shares the relevant overall sequence identity and/or sequence element with a reference mTOR polypeptide but not with a reference PI3K or PIKK polypeptide.

[0102] In many embodiments, an mTOR polypeptide includes one of more HEAT sequence elements, which are repeat-like a-helical structures which mediate protein-protein interactions.
[0103] In some embodiments, an mTOR polypeptide of interest may show three- dimensional similarity with one or more reference mTOR polypeptides and/or PI3K and/or PIKK polypeptides, but may or may not show a particular level of sequence identity or homology overall, or with respect to the relevant portion showing the three-dimensional similarity. For example, the catalytic domain of mTOR (SEQ ID NO: ( )) and PIK3C3 (SEQ ID NO: ( )) only share 24% sequence identity, but share a high degree of three-dimensional similarity, including the arrangement of key active site residues, when superpositioned bound to the same ATP TS mimic (For example, see Example 1 , FIG. 2C, FIG. 13C). In some embodiments, an mTOR polypeptide of interest shows three-dimensional similarity with one or more reference mTOR polypeptides with respect to at least one feature that is not shared with a reference PI3K and/or with a PIKK polypeptide; in some embodiments, the at least one feature is not shared with any known and/or wild type PI3K and/or PIKK polypeptide. [0104] Among other things, the present invention demonstrates that superimposition of provided mTOR structures can identify and/or characterize key residues and/or side chains in unknown structures. For example, superimposition of provided mTOR structures with known structures of CDK2 (SEQ ID NO: ( )) reveals that the arrangement of key active site residues is conserved in mTOR (see FIG. 2C, FIG. 13C) including Asn2342 and Asp2357, which serve as ligands for the two metal ions and Lys 2187, which coordinates the ATP phosphate group.
mTOR Asp2338, which is a key catalytic residue that helps orient and activate the substate hydroxyl group for nucleophilic attack, superimposed with CDK2 Aspl27. mTOR His2340, which interacts with both the substrate hydroxyl group and the γ-phosphate TS mimic to stabilize the buildup of charge at the transition state, superimposed with CDK2 lys 129 side chains (see FIG. 2C).
[0105] As described herein, among other things, the present invention defines certain mTOR structural elements that interact with modulators of interest. For example, in accordance with the present invention, one or more moieities within the mTOR ATP binding domain may mediate interaction with modulators of interest. Alternatively or additionally, in some embodiments, moieities at or near the mTOR catalytic loop and/or activation loop may mediate interaction with such modulators. In some embodiments, in accordance with the present invention, mTOR polypeptides are provided that include moieties corresponding to those defined herein as mediating interaction with modulators of interest. To give but a few examples, in some embodiments, provided mTOR polypeptides include residues corresponding to mTOR residues within a relevant portion of the mTOR ATP binding domain, catalytic loop domain, activation loop domain, the kaAL helix in the activation loop domain, FKBP12-rapamycin-binding domain (FRB), mLST8-binding element (LBE) domain, and/or combinations thereof. In some embodiments, provided mTOR polypeptides include residues corresponding to mTOR residues
SEQ ID NO: ( ) 2022-2118, 2259-2296, 2360-2370, 2164 -2172, 2332 -2346, 2357 -2379,
1376-2549, 1376-2443, 2443-2549, 1-2549, and/or combinations thereof. mTOR Funtion [0106] It is generally believed that mTOR plays a role in the development and function of the immune system, chromosome maintenance and repair, cell-cycle control, and tumor suppression. mTOR has been reported to have a variety of biological activities including, for example, promoting cell growth (e.g. promoting translation, ribosome biogenesis, autophagy), responding to growth factors, promoting cell-cycle entry, cell survival, actin cytoskeleton polarization, and anabolic output. According to some reports, mTOR is thought to integrate the input from multiple upstream pathways, including insulin, growth factor, and amino acids.
mTOR may be involved in sensing cellular nutrient, oxygen, and/or energy levels. mTOR is known to act via interaction with one or more binding partners. mTOR is the catalytic subunit of two multi-protein complexes, mTORCl and mTORC2. It has been reported that mTORCl and mTORC2 regulate processes that control cell growth and proliferation, including protein synthesis, autophagy, and metabolism. mTORCl phosphorylates the translational regulators S6 Kinase 1 (S6K1) and the eIF-4E binding proteins (4EBP1 and 4EBP2) while mTORC2 activates Akt and serum/glucocorticoid regulated kinase 1 (SGK1) and is part of the growth factor- stimulated phosphoinositide-3 -kinase (PI3K) pathway.
[0107] A variety of assays are known or have been developed that detect and/or characterize mTOR activities (Toral-Barza L, Zhang WG, Lamison C, Larocque J, Gibbons J, Yu K. Biochem Biophys Res Commun. 2005 Jun 24;332(1):304-10; Kim DH, Sarbassov DD, Ali SM, King JE, Latek RR, Erdjument-Bromage H, Tempst P, Sabatini DM. Cell 2002 Jul

18;307(5712): 1098-101). In some embodiments, mTOR activity is or comprises interacting with a particular binding partner or partners. In some embodiments, mTOR activity is or comprises discriminating between potential partners. In some embodiments, mTOR activity is or comprises mTORl activity. In some embodiments, mTOR activity is or comprises mTOR2 activity.
[0108] In some embodiments, mTOR activity is or comprises phosphorylation of a particular substrate or substrates. Despite the diverse process controlled by mTOR, few substrates are known. Known mTOR substrates include the translational regulators S6 Kinase 1 (S6K1), the eIF-4E binding proteins (4EBP1 and 4EBP2), Akt (Protein Kinase B; PKB) and serum/glucocorticoid regulated kinase 1 (SGK1).
[0109] In some embodiments, an mTOR polypeptide shares at least one of these activities with a reference mTOR polypeptide, such as a wild type mTOR. In some
embodiments, an mTOR polypeptide is considered to "share" an activity with a reference if it shows an activity that would be recognized by those skilled in the art as comparable to, or not significantly different from, that of a relevant reference in an appropriate assay that detects and/or characterizes the activity. While the kinase activity of an mTOR polypeptide compared to a reference may be significantly lower, it can be recognized by its ability to phosphorylate mTOR-specific sites in bona-fide mTOR substrates. One example of such site is the S6 Kinase 1 Thr389 site, which is not known to be phosphorylated substantially by any other kinase.

[0118] The present invention also provides structural information and/or analyses of mTOR polypeptide crystals and/or sets thereof.

In some embodiments, such graphical representations may include, for example, space-filling models, molecular surface representations, shell or boundary models, ribbon models, stick models; and/or combinations thereof.

In some embodiments, provided information is or comprises differences observed between or among structures that differ from one another in the presence or absence of one or more binding partners and/or one or more modulators.
[0120] In some embodiments, such structural information and/or analyses may be embodied in a tangible medium (e.g., a computer-readable medium) or a storage environment. Thus, the present invention provides tangible embodiments of mTOR polypeptide crystal structure information, as well as its use, for example, by or with a computer system, in any of a variety of applications. For example, in some embodiments, such structural information and/or analyses may be accessed by, transported to or from, and/or otherwise utilized by a computer system or program running thereon.
[0121] Among other things, the present disclosure embodies a recognition of the source of a problem with providing mTOR polypeptide crystals. mTOR has long known to be a protein of significant biological and pharmacological interest. Significant efforts have been made to obtain mTOR crystals, among other things in order to permit or inform effective drug discovery efforts. However, prior to the present disclosure, useful mTOR crystals have not been obtained, and crystal structure information has not been provided. Those interested in considering mTOR protein structure, for example in design and/or development of candidate mTOR modulators, have often been relegated to consulting crystal structures of related kinases such as PI3K kinases (there are no defined PIK kinase structures; one report of DNAPK electron density at 6.6 A resolution, which is not high enough resolution to define astructure). Comonly employed PI3K kinase structures include PI3K gamma (Liu Q, Wang J, Kang SA, Thoreen CC, Hur W, Ahmed T, Sabatini DM, Gray NS. J Med Chem. 2011 Mar 10;54(5): 1473-80; Finlay MR, Buttar D, Critchlow SE, Dishington AP, Fillery SM, Fisher E, Glossop SC, Graham MA, Johnson T, Lamont GM, Mutton S, Perkins P, Pike KG, Slater AM.

Bioorg Med Chem Lett. 2010 Apr l;20(7):2321-5.).
[0122] As described herein, the present disclosure recognizes that one problem with prior efforts to provide mTOR polypeptide crystals is that the utilized mTOR polypeptides were not amenable to crystallization. Among other things, the present invention provides crystallizable mTOR polypeptides, systems for producing them, methods of utilizing them, and crystals thereof.
[0123] For example, the present invention provides truncated and/or internally deleted mTOR polypeptides that are amenable to crystallization. In some embodiments, the present invention provides an mTOR polypeptide, wherein the N-terminus has been deleted. In some embodiments, provided mTOR polypeptides comprise both an N-terminus deletion and an internal deletion. In some embodiments, provided mTOR polypeptides comprise both an N- terminus deletion and an internal deletion of residues 2443-2486. Without wishing to be bound by any particular theory, truncation and/or internal deletion of the mTOR polypeptide favors crystallization because it can reduce flexibility, can result in more compact shape, and eliminate undesirable events like aggregation, if for example, the deleted region has a hydrophobic binding site for a protein-binding partner.
[0124] The present disclosure also recognizes that one problem associated with prior efforts to provide mTOR polypeptide crystals is that the utilized expression systems often did not effectively produce crystallizable mTOR polypeptides. Preparing protein crystals appropriate for X-ray diffraction usually requires a considerable amount of highly purified protein. Polypeptides for crystallization are often expressed in well-established microbial systems such as Escherichia coli. Polypeptide expression in microbial systems is well-established, fast, simple and usually provides high yields. However, microbial systems lack the chaperones required for folding complex eukaryotic proteins are not able to perform specific eukaryotic post-translational modifications. Alternatively, in some cases polypeptide expression in insect baculovirus systems is used, nsect baculovirus systems are of an evolutionary higher order, and have fewer problems associated with producing the protein in its native state, however expressing large amounts of material in an easy-to-purify form becomes more difficult.
[0125] The present invention encompasses the recognition that neither microbial or baculovirus expression systems may be optimal for expression of mTOR polypeptides, and particularly for expression of crystalizable mTOR polypeptides.
[0126] Among other things, the present invention provides mammalian cells, and particularly human cells, engineered to express an mTOR polypeptide. In some embodiments, provided mammalian cells are human HEK293-F cells.
[0127] In some embodiments, crystallizable or crystallized mTOR polypeptides provided by the present invention are recombinant polypeptides in that they are produced by cells engineered to express them.
[0128] In some embodiments, crystallizable or crystallized mTOR polypeptides provided by the present invention are purified recombinant polypeptides.
[0129] mTOR polypeptide crystals, for example as provided by the present invention, reveal various interesting attributes of the mTOR polypeptide and/or its interactions with other agents. Provided information includes, for example, the insight that mTOR-mLST8 complex is instrinsically active in the absence of additional regulatory subunits and that PBKs emply the same catalytic mechanism as canonical protein kinases, in contrast to art-accepted mechanisms32
[0130] The present invention surprisingly demonstrates that crystals can be obtained of mTOR polypeptides that diffract with a resolution higher than about 4 A. The present invention provides such crystals. In some embodiments, for example, the present invention provides mTOR polypeptide crystals that diffract to a resolution within about 3.0 to about 3.5 A. In some embodiments, the present invention provides mTOR polypeptide crystals that diffract to a resolution higher than about 3.5 A , about 3.4 A , about 3.3 A , about 3.2 A, about 3.1 A, about 3.0 A, or higher.
Structure-Based Drug Design
[0131] The mTOR kinase is a master regulator of cell growth, and is the focus of anticancer drug discovery efforts. Findings described herein permit design of modulators with specified characteristics that can interact with mTOR polypeptides. For example, the
information provided by mTOR crystal structures described herein permits molecular modeling and/or design of potential binding agents that can interact with sites of interest within an mTOR polypeptide.
[0132] Among other things, the present disclosure identifies the source of a problem with prior efforts to identify, characterize, and/or develop mTOR modulators. Currently FDA- approved mTOR inhibitors are based on the natural compound rapamycin, which was thought to be an allosteric inhibitor. The present invention provides, among other things, the identification of a source of a problem with understanding of rapamycin, its mechanism, and its effectiveness as an mTOR inhibitors. As described herein, we have demonstrated that rapamycin blocks a substrate -binding site on the mTOR kinase.
[0133] Rapamycin, which forms a ternary complex with the FK506-binding proteinl2
(FKBP12) and the FRB (FKBP12-Rapamycin-Binding) domain of mTOR, has been thought to be an allosteric inhibitor24'25. Rapamycin-FKBP12 inhibits mTORCl to a variable extent that is substrate and phosphorylation- site dependent25, and it does not bind to mTORC223. To overcome these limitations, ATP-competitive inhibitors that potently and uniformly inhibit both mTORCl and mTORC2 are being developed as anti-cancer agents26.
[0134] Several groups have programs to develop mTOR inhibitors that target the ATP- binding site of the kinase, and many of these are in clinical trials. The present invention encompasses the recognition that such discovery efforts could be materially enhanced if a crystal structure for mTOR, or even for one or more mTOR-related kinases were available. As noted above, mTOR belongs to the PIK (Phosphatidyl-Inositol 3 Kinase (PI3K)-like protein Kinase) family of kinases; no structures are available for kinases in this family. The closest kinase of a known structure is the phosphatidyl-inositol 3 kinase (PI3K) itself, but it has not been a good model for understanding the potency and specificity of mTOR inhibitors. [0135] Unfortunately, many available mTOR inhibitors have been found to have limited clinical efficacy. Without wishing to be bound by any particular theory, the present invention suggests that such limited clinical efficacy may result from incomplete and/or substrate- dependent inhibition.
[0136] The present invention recognizes that, in many embodiments, effective mTOR modulators interact with at least one other site within an mTOR complex in addition to the mTOR ATP-binding site.
[0137] In some embodiments, the present disclosure provides systems for identifying and/or characterizing mTOR inhibitors.
[0138] Representative known mTOR modulators are presented in Table 12; the present disclosure does not encompass such known mTOR modulating agents. However, the present invention does encompass use of agents whose structure or identity was previously known (and was known to be within the scope of modulator structure(s) as defined herein), but whose activity modulating mTOR was not previously known.
Computer Systems
[0139] As will be appreciated by those skilled in the art, reading the present disclosure, in some aspects, the present invention is ideally suited for use in computer-implemented inventions. FIG. 24 shows but one example of a computing device 2500 and a mobile computing device 2550 that can be used to implement certain techniques described in this disclosure. The computing device 2500 depicted in FIG. 24 is intended to represent any of a variety forms of digital computers, such as laptops, desktops, workstations, personal digital assistants, servers, blade servers, mainframes, and other appropriate computers. The depicted mobile computing device 2550 is intended to represent any appropriate form of mobile devices, such as personal digital assistants, cellular telephones, smart-phones, tablet computers, and other similar computing devices. Moreover, the components shown in FIG. 24 and elsewhere in the Figures, their connections and relationships, and their functions, are meant to be examples only, and are not meant to be limiting. [0140] The computing device depicted in FIG. 24 2500 includes a processor 2502, a memory 2504, a storage device 2506, a high-speed interface 2508 connecting to the memory 2504 and multiple high-speed expansion ports 2510, and a low-speed interface 2512 connecting to a low-speed expansion port 2514 and the storage device 2506. Each of the processor 2502, the memory 2504, the storage device 2506, the high-speed interface 2508, the high-speed expansion ports 2510, and the low-speed interface 2512, are interconnected using various busses, and may be mounted on a common motherboard or in other manners as appropriate. The processor 2502 can process instructions for execution within the computing device 2500, including instructions stored in the memory 2504 or on the storage device 2506 to display graphical information for a GUI on an external input/output device, such as a display 2516 coupled to the high-speed interface 2508. In some implementations, multiple processors and/or multiple buses may be used, as appropriate, along with multiple memories and types of memory. Also, multiple computing devices may be connected, with each device providing portions of the necessary operations (e.g., as a server bank, a group of blade servers, or a multi-processor system).
[0141] The memory 2504 depicted in FIG. 24 stores information within the computing device 2500. In some implementations, the memory 2504 is a volatile memory unit or units. In some implementations, the memory 2504 is a non-volatile memory unit or units. The memory 2504 may also be another form of computer-readable medium, such as a magnetic or optical disk.
[0142] The storage device 2506 depicted in FIG. 24 is capable of providing mass storage for the computing device 2500. In some implementations, the storage device 2506 may be or contain a computer-readable medium, such as a floppy disk device, a hard disk device, an optical disk device, or a tape device, a flash memory or other similar solid state memory device, or an array of devices, including devices in a storage area network or other configurations.
Instructions can be stored in an information carrier. The instructions, when executed by one or more processing devices (for example, processor 2502), perform one or more methods, such as those described above. The instructions can also be stored by one or more storage devices such as computer- or machine-readable mediums (for example, the memory 2504, the storage device 2506, or memory on the processor 2502).
[0143] The high-speed interface 2508 manages bandwidth-intensive operations for the computing device 2500, while the low-speed interface 2512 manages lower bandwidth-intensive operations. Such allocation of functions is an example only. In some implementations, the highspeed interface 2508 is coupled to the memory 2504, the display 2516 (e.g., through a graphics processor or accelerator), and to the high-speed expansion ports 2510, which may accept various expansion cards (not shown). In the implementation, the low-speed interface 2512 is coupled to the storage device 2506 and the low-speed expansion port 2514. The low-speed expansion port 2514, which may include various communication ports (e.g., USB, Bluetooth®, Ethernet, wireless Ethernet) may be coupled to one or more input/output devices, such as a keyboard, a pointing device, a scanner, or a networking device such as a switch or router, e.g., through a network adapter.
[0144] The computing device 2500 may be implemented in a number of different forms, as shown in the figure. For example, it may be implemented as a standard server 2520, or multiple times in a group of such servers. In addition, it may be implemented in a personal computer such as a laptop computer 2522. It may also be implemented as part of a rack server system 2524. Alternatively, components from the computing device 2500 may be combined with other components in a mobile device (not shown), such as a mobile computing device 2550. Each of such devices may contain one or more of the computing device 2500 and the mobile computing device 2550, and an entire system may be made up of multiple computing devices communicating with each other.
[0145] The mobile computing device 2550 depicted in FIG. 24 includes a processor
2552, a memory 2564, an input/output device such as a display 2554, a communication interface 2566, and a transceiver 2568, among other components. The mobile computing device 2550 may also be provided with a storage device, such as a micro-drive or other device, to provide additional storage. Each of the processor 2552, the memory 2564, the display 2554, the communication interface 2566, and the transceiver 2568, are interconnected using various buses, and several of the components may be mounted on a common motherboard or in other manners as appropriate.
[0146] The processor 2552 depicted in FIG. 24 can execute instructions within the mobile computing device 2550, including instructions stored in the memory 2564. The processor 2552 may be implemented as a chipset of chips that include separate and multiple analog and digital processors. The processor 2552 may provide, for example, for coordination of the other components of the mobile computing device 2550, such as control of user interfaces, applications run by the mobile computing device 2550, and wireless communication by the mobile computing device 2550.
[0147] The processor 2552 may communicate with a user through a control interface
2558 and a display interface 2556 coupled to the display 2554. The display 2554 depicted in FIG. 24 may be, for example, a TFT (Thin-Film-Transistor Liquid Crystal Display) display or an OLED (Organic Light Emitting Diode) display, or other appropriate display technology. The display interface 2556 may comprise appropriate circuitry for driving the display 2554 to present graphical and other information to a user. The control interface 2558 may receive commands from a user and convert them for submission to the processor 2552. In addition, an external interface 2562 may provide communication with the processor 2552, so as to enable near area communication of the mobile computing device 2550 with other devices. The external interface 2562 may provide, for example, for wired communication in some implementations, or for wireless communication in other implementations, and multiple interfaces may also be used.

mTor modulators
[0172] As described herein, the present disclosure provides methodologies, technologies, and systems for designing and/or characterizing mTOR polypeptide modulators. The macrolide rapamycin is a selective and allosteric inhibitor of the mTORCl complex but not the mTORC2 complex. There is therefore a need to develop small molecule modulators that target both mTORCl and mTORC2 complexes.
[0173] In some embodiments, provided modulators have a structure comprising one or more of the following features: [0174] A) a moiety that fits in the mTOR adenosine (ATP) binding site and may make one or two hydrogen bonds to main chain groups of the "hinge" extending from Gly2238 to Val2240. In some embodiments, moieties can be any one of well-characterized pharmacophores like pyrazolopyrimidines that have been developed as adenosine-site mimics for Ser/Thr/Tyr and PI3 kinases.
[0175] B) a moiety that stacks with tryptophan (Trp2239). In some embodiments, moities can be a ring structure that is fused to the ring structure of (A), or it can be attached to (A) in other ways.
[0176] C) a moiety that binds to the "inner hydrophobic pocket" formed by mTOR residues Tyr2225, Val2227, Met2199, Ile2237, Ile2356, Phe2358, Leu2192, Asp2195, Asp2357 and Gly2359. In some embodiments, one or more of these residues have at least two
conformations shown by the structure of mTORDn-mLST8 bound to PP242 inhibitor, and either conformation can be used in modulator design and/or characterization.
D) a moiety that binds to the N-lobe hydrophobic pocket (Ile2163, Pro2169 and
Leu2185). In some embodiments, when B and C are both present, the modulator is arranged and constructed such that, when it is bound to mTOR, B and C are arranged in three dimensional space relative to one another on opposite sides of A. When D is present, it will extend from A or from B orthogonal to the B-A-C line.

[0178] In some embodiments, provided modulators are characterized by desirable mTOR modulating activity. For example, in some embodiments, provided modulators are characterized in that, when the modulator is contacted with an assay system that contains or is capable of producing an mTOR polypeptide and permits detection and/or quantitation of level and/or activity of the mTOR polypeptide, the detected such level or activity is different when the modulator is present as compared with when it is absent.
[0179] In some embodiments, the assay system comprises an isolated mTOR
polypeptide. In some embodiments, the assay system comprises one or more cells that can or do produce an mTOR polypeptide. In some embodiments, the assay systems include, but are not limited to any microbial cell, insect cell, mammalian cell, and/or combinations thereof, that can or do produce an mTOR polypeptide. Assay systems useful in detecting and/or characterizing mTOR modulator activity as described herein include in vitro kinase assyas using S6K1, 4EBP1 or other mTOR substrates, or cell-based assays using immunoblotting with antibodies specific to phosphosylated forms of S6K1, 4EBP1 or other mTOR substrates, or other mTOR assays such as cell growth and proliferation commonly reported in the literature.
[0180] In some embodiments, an mTOR modulator as described herein is an agent whose presence correlates with a level of mTOR activity that is at least about 1000, 900, 800, 700, 600, 500, 400, 300, 200, 100, 90, 80, 70, 60, 50, 40, 30, 20, 10, 9, 8, 7, 6, 5, 4, 3, or 2 fold higher or lower in a given assay than that observed under otherwise comparable conditions than that observed absent the modulator.
[0181] In some embodiments, an mTOR modulator as described herein impacts mTOR activity in a way or to a degree comparable to or greater than that of a reference mTOR modulator. In some embodiments, a provided mTOR modulator correlates with an increase or decrease of mTOR activity that is within 10%, 20%, 305, 40%, 50%, 60%, 70%, 80%, 90%, 100%, 200%, 300%, 400%, 500%, 600%, 700%, 800%, 900%, 1000% or more of that observed with such reference mTOR modulator.
[0182] In some embodiments, provided modulators are ATP-competitive modulators.
[0183] In some embodiments, a reference mTOR modulator is one included in Table 12.
In some embodiments, a reference mTOR modulator includes, but is not limited to, rapamycin, PI 103 HCL, AZD8055, AZD2014, CH5132799, XL765 (SAR245409), GDC-0980 (RG7422), GSK1059615, GSK2126458, Torinl , Torin2, INK128, KU0063794, BEZ235 (NVP-BEZ235), NVP-BGT226, OSI-027, Palomid 529, PF-05212384 (PKI-587), PKI-179, WAY-600, WYE- 125132 (WYE-132), WYE-23, WYE-28, WYE-354, WYE-687, PF-04691502, PP-121 , PP242, and/or PP30.

In an assay system that detects and/or quantifies an activity of the mTOR polypeptide, the modulator increases or decreases detected activity of the mTOR polypeptide, for example by increasing or decreasing mTOR polypeptide level and/or activity.
[0184] One aspect of the present invention surprisingly establishes that many theories about interaction of mTOR modulators (e.g., inhibitors) with mTOR have been mistaken. For example, the high affinity of Torin2 for mTOR was proposed, based on a PBKgamma-derived mTOR model, to be due to a pair of hydrogen bonds that are not there in the mTORDn-mLST8- Torin2 structure. Among other things, the present invention establishes that the high affinity and specificity is due primarily to the extensive stacking of the tricyclic benzonapththyridine ring of Torin2 with the indole group of Trp2239 of mTOR, and secondarily the packing of the Torin2 trifluoromethyl group into the aforementioned N lobe hydrophobic pocket (Figure 6A). In another example, the high affinity and specificity of PP242 for mTOR was not understood, as the paper reporting it noted. The mTORDN-mLST8-PP242 structure showed that the inhibitor causes a conformational change in the inner hydrophobic pocket that is coupled to the binding of the PP242 hydroxyindole group there.
[0185] The present invention defines interaction sites within mTOR polypeptides that, when targeted, can achieve potent and/or selective modulation of mTOR activity. Among other things, the present invention establishes the arrangement and positions of chemical groups that make up the mTOR active site, and how they can be targeted for interactions by inhibitors.
[0186] The present invention therefore defines important structural features of mTor modulating agents. For example, according to the present invention, certain desirable modulating agents have a chemical structure of the form
D or D I I
B A C wherein:
A is a moiety that fits in the mTOR adenosine (ATP) binding site and may make one or two hydrogen bonds to main chain groups of the "hinge" extending from Gly2238 to Val2240;
B is a moiety that stacks with tryptophan (Trp2239) and optionally comprises a ring structure that is fused to the ring structure of (A), and/or B can be attached to (A) in other ways; C is a moiety that binds to the "inner hydrophobic pocket" formed by mTOR residues Tyr2225, Val2227, Met2199, Ile2237, Ile2356, Phe2358, Leu2192, Asp2195, Asp2357 and Gly2359; in some embodimetns, one or more of these residues have at least two conformations shown by the structure of mTORDn-mLST8 bound to PP242 inhibitor; and
D is a moiety that binds to the N-lobe hydrophobic pocket (Ile2163, Pro2169 and Leu2185); in some embodiments, when B and C are both present, the modulator is arranged and constructed such that, when it is bound to mTOR, B and C are arranged in three dimensional space relative to one another on opposite sides of A. When D is present, it will extend from A or from B orthogonal to the B-A-C line.

Pharmaceutically acceptable preparations and salts of the active agent are provided herein and are well known in the art. For the administration of mTOR modulators and the like, the amount administered desirably is chosen that is
therapeutically effective with few to no adverse side effects. The amount of the therapeutic or pharmaceutical composition which is effective in the treatment of a particular disease, disorder or condition depends on the nature and severity of the disease, the target site of action, the subject's weight, special diets being followed by the subject, concurrent medications being used, the administration route and other factors that are recognized by those skilled in the art. The dosage can be adapted by the clinician in accordance with conventional factors such as the extent of the disease and different parameters from the subject. Effective doses may be extrapolated from dose-response curves derived from in vitro or animal model test systems (e.g., as described by the U.S. Department of Health and Human Services, Food and Drug Administration, and Center for Drug Evaluation and Research in "Guidance for Industry: Estimating Maximum Safe Starting Dose in Initial Clinical Trials for Therapeutics in Adult Healthy Volunteers",
Pharmacology and Toxicology, July 2005, the entire contents of which are incorporated herein by reference).
[0191] Various delivery systems are known and can be used to administer active agent described herein (e.g. mTOR modulators) or a pharmaceutical composition comprising the same. The pharmaceutical compositions described herein can be administered by any suitable route including, intravenous or intramuscular injection, intraventricular or intrathecal injection (for central nervous system administration), orally, topically, subcutaneously, intrapulmonary {e.g., inhalation), subconjunctivally, intraocularly, or via intranasal, intradermal, sublingual, vaginal, rectal or epidural routes.
[0192] Other delivery systems well known in the art can be used for delivery of the pharmaceutical compositions described herein, for example via aqueous solutions, encapsulation in microparticules, or microcapsules. The pharmaceutical compositions of the present invention can also be delivered in a controlled release system. For example, a polymeric material can be used (see, e.g., Smolen and Ball, Controlled Drug Bioavailability, Drug product design and performance, 1984, John Wiley & Sons; Ranade and Hollinger, Drug Delivery Systems, pharmacology and toxicology series, 2003, 2nd edition, CRRC Press). Alternatively, a pump may be used (Saudek et al, N. Engl. J. Med. 321 :574 (1989)). The compositions described herein may also be coupled to a class of biodegradable polymers useful in achieving controlled release of the drug, for example, polylactic acid, polyorthoesters, cross-linked amphipathic block copolymers and hydrogels, polyhydroxy butyric acid, and polydihydropyrans.
[0193] As described above, pharmaceutical compositions desirably include a
pharmaceutically acceptable carrier. The term carrier refers to diluents, adjuvants, excipients or vehicles with which mTOR modulators are administered. Such pharmaceutical carriers include sterile liquids such as water and oils including mineral oil, vegetable oil (e.g., soybean oil or corn oil), animal oil or oil of synthetic origin. Aqueous glycerol and dextrose solutions as well as saline solutions may also be employed as liquid carriers of the pharmaceutical compositions of the present invention. The choice of the carrier depends on factors well recognized in the art, such as the nature of the peptide, peptide derivative or peptidomimetic, its solubility and other physiological properties as well as the target site of delivery and application. Examples of suitable pharmaceutical carriers are described in Remington: The Science and Practice of Pharmacy by Alfonso R. Gennaro, 2003, 21th edition, Mack Publishing Company. Moreover, suitable carriers for oral administration are known in the art and are described, for example, in U.S. Patent Nos. 6,086,918, 6,673,574, 6,960,355, and 7,351,741 and in WO2007/131286, the disclosures of which are hereby incorporated by reference. [0194] Further pharmaceutically suitable materials that may be incorporated in pharmaceutical preparations include absorption enhancers including those intended to increase paracellular absorption, pH regulators and buffers, osmolarity adjusters, preservatives, stabilizers, antioxidants, surfactants, thickeners, emollient, dispersing agents, flavoring agents, coloring agents, and wetting agents.

Exemplification
Example 1: Expression and Crystallization of an mTOR Polypeptide, mTOR
[0240] The mammalian target of rapamycin (mTOR), a phosphoinositide 3-kinase related protein kinase (PIK ), controls cell growth in response to nutrients and growth factors and is frequently deregulated in cancer. The present Example describes development of an expression system that permits crystallization of a truncated mTOR polypeptide, containing all regions common to PIKKs, and further permits determination of the structure of crystals of the mTOR polypeptide bound to the activating mLST8 subunit and to an ATP transition state mimic. The determined structures reveal an intrinsically active kinase conformation, with catalytic residues and mechanism remarkably similar to canonical protein kinases. The active site is highly recessed due to the FKBP12-Rapamycin binding (FRB) domain and an inhibitory helix protruding from the catalytic cleft. mTOR activating mutations map to the structural framework that holds these elements in place, indicating that the kinase is controlled by restricted access. In vitro biochemistry indicates that the FRB domain acts as a gatekeeper, with its rapamycin- binding site interacting with substrates to grant them access to the restricted active site. The FKBP12-rapamycin complex inhibits by directly blocking substrate recruitment and by further restricting active site access.
[0241] Specifically, the present Example presents the 3.2 A crystal structure of an -1500 amino acid mTOR polypeptide-mLST8 complex containing the FAT, FRB, kinase and FATC domains, as well as the structures of this complex bound to an ATP transition state analog and to ATP-competitive inhibitors. We discuss their implications for understanding mTOR function, regulation and inhibition by rapamycin and ATP-competitive compounds. Overall structure of mTOR -mLST8
[0242] Crystals were grown using an N-terminally truncated human mTOR (residues
1376 to 2549; thereafter mTORAN) bound to full-length human mLST8 (FIG. 7). The complex was produced in an HEK293-F cell line that was stably-transfected sequentially by FLAG-tagged mLST8 and FLAG-tagged mTORAN vectors. The kinase activity of mTORAN-mLST8 is overall comparable to that of mTORCl (FIG. 10). mTORCl is more active towards lowmicromolar concentrations of S6Klkl (kinase-inactive mutant) and 4EBP1, consistent with RAPTOR recruiting these substrates through their TOS motifs, whereas mTORAN-mLST8 is more active at higher substrate concentrations.
[0243] The mTORAN-mLST8 structure has a compact shape (FIG. 1 A). The FAT domain, which consists of α-α helical repeats, forms a "C" shaped a solenoid that wraps halfway around the kinase domain and clamps on it (FIG. IB). mLST8 and the FRB domain protrude from the kinase domain, on opposite sides of the catalytic cleft. The FATC is integral to the kinase domain structure.
[0244] The -550-residue mTOR kinase domain (KD) adopts the two-lobe structure that is characteristic of both the PI3K and canonical protein kinase families29. It consists of an N- terminal lobe (N lobe) rich in β sheet, a larger C-terminal lobe (C lobe), and a cleft in-between the two that binds to ATP. It shares a core structure with PI3K KD fold, but with substantial differences. While the KD structures of the five PI3Ks superimpose on each other essentially across their entire -350 residues, only -250 residues of the mTOR KD align with PI3Ks (FIG. 8). In addition, the mTOR KD contains -200 additional residues in unique structural elements that decorate the common fold. The largest of these is the FRB domain (residues 2021 to 2118) that is inserted within the kinase N lobe (FIG. 1 A). There is also a -40 residue insertion in the C lobe that forms the binding site for mLST8 (residues 2258 to 2296; thereafter LBE).
Kinase domain structure
[0245] The mTOR KD structure starts prior to the FRB domain, with the long kal helix that is present in PI3Ks as well (FIG. 2A and FIG. 11 A). The kal helix is integral to the structure of the N lobe, as it packs in the concave surface of the 5-stranded N lobe β sheet in both mTOR and PBKs29. The FRB insertion occurs immediately after kal, in an area where PBKs contain a short crossover loop to a ka2 helix that packs with k l . In mTOR, the PBK ka2 is replaced by a β strand and by two short helices that pack with the base of the FRB. Thereafter, the mTOR and PBK N lobes share a similar structure across the kBl-kB7 sheet and the intervening ka3 helix.
[0246] The mTOR structure indicates that the k l helix is present in the remainder of
PIKKs as well (FIG. 12A). The SMG1, DNAPKcs and TRRAP PIKKs also appear to have an FRB-like domain, as they contain insertions of 128, 95 and 128 residues, respectively, that are predicted to be alpha-helical. This is supported by the 6.6 A x-ray diffraction data of DNAPKcs reported recently30. Although the deposited model, which contains a PBK-derived kinase domain, lacks the FRB insertion, a reinterpretation of the data using the mTOR structure reveals strong Fo-Fc electron density indicative of an FRB-like four-helix bundle (FIG. 12B). ATM and ATR appear to lack a comparable insertion.
[0247] In the C lobe, the vicinity of the catalytic cleft contains four structural insertions compared to PBKs (LBE, kaAL, ka9b and FATC; FIG. 2A). These form a spine of interactions centered on the activation loop, which is a ~30 residue segment with a central role in the function and regulation of canonical protein kinases. It forms part of the polypeptide binding site, provides an active site residue, and also undergoes a conformational change, typically disorder- to-order transition, upon kinase activation31. The activation loop is thought to have an analogous role in PBKs, among which only in the class 3 PIK3C3/Vps34 structures it is ordered32. In the mTOR structure the entire activation loop is well-ordered (FIG. 1 IB), and its middle portion contains the kaAL helix insertion. One side of the activation loop packs with the ka9b insertion, and the other side with the FATC (FIG. 11 A). The FATC is not unique to PIKKs in its entirety, as its N-terminal half forms a helix (kal 1) that is also present in PBK structures29'32. Its C- terminal half, which is absent from PBKs, forms three short helices that pack with the activation loop on one side and the LBE on the other (Fig. 2a).
[0248] The interactions the FATC makes with the activation loop suggest that it may have a role in stabilizing the activation loop structure, and the LBE, through its interactions with the FATC, may contribute to this indirectly (FIG. 13 A). Consistent with this notion, the FATC and activation loop sequences are highly conserved among PIK s. While the LBE is not conserved, all PIKK family members contain an LBE-like insertion that may similarly pack with FATC (FIG. 12A).
[0249] The ka9b insertion (residues 2425 to 2436) plugs one end of the catalytic cleft
(FIG. 11 A). It partially overlaps with a segment, termed negative regulatory domain (residues
33 34 35
2430 to 2450), whose deletion activates mTOR in vitro and in vivo ' . After ka9b, there is a 55 residue unstructured segment (2437 to 2491) that is not conserved and has variable length in mTOR orthologs (FIG. 11 A).
Active site conformation
[0250] To assess the activation state of the KD structure and investigate the mechanism of phosphotransfer, we co- crystallized mTORAN-mLST8 with ADP, Mg2+ and MgF3 ", a mimic of the γ-phosphate group of ATP in the transition state (TS)36 (FIG. 7). The 3.5 A Fo-Fc map of these crystals shows strong electron density extending -from the B-phosphate group of ADP, consistent with a bound MgF3 group (FIG. 2B). The presence of two additional Mg2+ ions is supported by the anomalous dispersion maps of apo-crystals soaked in AMPPNP-Mn2+ (FIG. 13B).
[0251] A superposition with the canonical protein kinase CDK2 bound to the same ATP
TS mimic36 reveals that the arrangement of key active site residues is conserved in mTOR (FIG. 2C and FIG. 13C). These include the C lobe Asn2343 and Asp2357, which serve as ligands for the two metal ions, and the N lobe Lys2187, which coordinates the ATP phosphate groups. In addition, Asp2338 superimposes remarkably well with the CDK2 Aspl27, which is a key catalytic residue that helps orient and activate the substrate hydroxyl group for nucleophilic attack36'37. The mTOR-CDK2 superposition also reveals a coincidence of the mTOR His2340 and CDK2 Lysl29 side chains (FIG. 2C). In protein kinases, a basic residue at this position interacts with both the substrate hydroxyl group and the γ-phosphate TS mimic, and is postulated to stabilize the buildup of charge at the transition state36'37. Consistent with a similar role, we find that the kinase activity of the H2340A mTOR -mLST8 mutant is barely detectable, and comparable to the D2338A mutant previously shown to be inactive38 (FIG. 13D).
[0252] These findings strongly suggest that the crystallized mTORAN-mLST8 complex is intrinsically active in the absence of any additional regulatory subunits. They also indicate that PIKKs, and most likely PBKs, employ the same catalytic mechanism as canonical protein kinases, in contrast to a recently-proposed PI3K mechanism32 (see legend of FIG. 13C).
Substrate-binding site
[0253] The ATP TS γ-phosphate group mimic points to an extended C lobe groove that is highly conserved and is the likely site of substrate binding. FIG. 2D illustrates this with a CDK2 -bound substrate peptide docked by superposing the mTOR and CDK2 TS36 complexes. The groove consists of the activation loop, as in canonical protein kinases, but also of portions of the FATC and LBE.
[0254] In the (+) direction (C-terminal to phosphorylation site), the groove extends only to the +1 position, abruptly terminating with the ka9b helix that plugs this end of the cleft (FIG. 2D). Thereafter, the peptide can exit following the surface of the C lobe towards mLST8, or along the N lobe and towards the FRB. The +1 portion of the groove has a pronounced pocket lined with three aromatic residues, consistent with the two classes of mTOR substrates, exemplified by 4EBP1 and S6K1, having a proline and tyrosine residue, respectively, at +1 (FIG. 15A and FIG. 15B). The groove extends substantially more in the (-) direction, and it may account for the low-level sequence preference at -4 and -5 suggested by a positional scanning peptide array39 (FIG. 2D).
Restricted access to the active site
[0255] The four-helix bundle FRB substantially extends the N lobe side of the catalytic cleft, running roughly parallel to the C lobe platform and mLST8 on the other side of the cleft. This gives the cleft a deep, "V"-shaped cross-section, restricting access to the substrate-binding site at the bottom of the cleft (FIG. 3A). Substrate access is further hindered by one end of the cleft being plugged by ka9b and the following 55 -residue unstructured segment. The deletion that defined the negative regulatory region33"35 (residues 2430 to 2450) encompasses 7 of 12 ka9b residues and 14 of 55 unstructured-segment residues. We find that deleting the bulk of the unstructured segment (44 residues; 2443-2486) does not activate mTOR (FIG. 15), suggesting that ka9b is the key element within the negative regulatory domain.
[0256] While the end of the cleft opposite from ka9b is unencumbered in the mTORAN- mLST8 structure, it is near the FAT N-terminus, and the region deleted from the crystallized mTOR may restrict cleft access directly and/or through its associated RAPTOR or RICTOR proteins. In support, we find that towards TOS-mutant 4EBP1 and ΞβΚΙ^ substrates, mTORAN- mLST8 is more active than mTOR-mLST8, which in turn is more active than mTOR-mLST8- RAPTOR (FIG. 15). A restricted active site would reduce the probability of substrates hitting the active site by random diffusion, and could thus be important in allowing for the regulation of phosphorylation by substrate-recruitment.
Inhibition by rapamycin-FKBP12
[0257] In a model constructed by superposing the FRB domains of the FRB-rapamycin-
FKBP1224 and mTORAN-mLST8 structures, FKBP12 extends from the FRB on the N lobe towards mLST8 on the C lobe, nearly capping the catalytic cleft (FIG. 3B). At their closest approach, FKBP12 and mLST8 are only 8 A apart, with the catalytic center recessed by 37 A. The model suggests that rapamycin-FKBP12 inhibits in part by drastically reducing the accessibility of the already constricted catalytic cleft. This is consistent with the extent of mTORCl inhibition being substrate and phosphorylation site dependent25.
[0258] In mTORC2, which is not inhibited by nanomolar rapamycin, there may not be enough space for rapamycin-FKBP12 to access the binding site on the FRB due to the proximity of other mTORC2 components. Consistent with the model that it is the FKBP12 component of rapamycin-FKBP12 that precludes binding to mTORC2, rapamycin can inhibit mTORC2 at micromolar concentrations, when it can bind to the FRB in the absence of FKBP12Supp 4. Also consistent with this model is the reduction in mTORC2 levels upon prolonged incubation with nanomolar rapamycinSupp'5, presumably because the de novo assembly of RICTOR with mTOR, which will now be bound to FKBP12-rapamycin, is blocked.
[0259] Prolonged rapamycin exposure can also destabilize the association of mTOR with
RAPTORSupp 6' Supp 7, as well as a dimeric arrangement of mTORCl Supp'8, although neither of these effects are observed with yeast TORClSupp 9' Supp l°. It is conceivable that RAPTOR is close enough to the active site that there is barely enough space for FKBP12-rapamycin to fit in. Any residual steric hindrance may destabilize mTOR-RAPTOR during the binding equilibrium of the complex. FRB recruits S6K1 to active site
[0260] The rapamycin-binding site maps to the FRB surface closest to the active site, in the midst of a hotspot of highly conserved residues (FIG. 4A). Four of these residues are invariant in 22 mTOR orthologs from yeast to man (Ser2035, Phe2039, Trp2102, Phe2108), and another four in 21 (Arg2036, Gln2099, Asp2102, Tyr2105), in stark contrast to the FRB surface opposite from the active site (FIG. 4A and FIG. 16). This raises the possibility that the rapamycin-binding site interacts with substrates to facilitate their entry to the recessed active site.
[0261] This model is supported by the observation that mutation of Ser2035, a rapamycin contact at the centre of the conservation hotspot38'40, reduces phosphorylation of S6K1 and 4EBP133. It can also explain inhibition of mTORCl and mTORC2 by rapamycin in the absence of FKBP12, albeit at ~ 100-fold higher micromolar concentrations reflecting the weaker rapamycin-FRB binary interaction41. However, these observations can also be explained by the rapamycin-binding site interacting with other parts of mTOR, or with associated proteins, especially since rapamycin was thought to be an allosteric inhibitor25. To rule this out, we assayed mTORAN-mLST8, and found that rapamycin but not the closely-related FK506 macrolide inhibits S6Klkl overall phosphorylation, as measured by 32P incorporation (FIG. 4B). Inhibition reaches ~45 % at the 20 μΜ solubility limit of rapamycin, close to the free rapamycin- FRB Kd. Phosphorylation of the key Thr389 site of the S6K1 HM motif, measured by a phosphoT389-specific antibody, is inhibited by -80 % (FIG. 4B). The ~150-residue C-terminal tail of S6K1 contains additional in vitro phosphorylation sites, although most are of unknown significance33'42.
[0262] In a complementary approach, we tested whether the isolated FRB domain inhibits phosphorylation in trans. FIG. 4C shows that wild type but not the S2035I FRB mutant38'40 inhibits overall S6Klkl phosphorylation by ~50 % and Thr389 phosphorylation by ~75 % at the highest concentration tested. Half-maximal inhibition occurs at ~ 100-200 μΜ FRB. This may underestimate the FRB-S6K1 affinity, however, as the isolated FRB-S6K1 association would have to compete with the bivalent binding of both the FRB and active site of mTORAN to S6Kl .
Ill [0263] To map the region of S6K1 involved in FRB interactions, we reasoned that its deletion should reduce Thr389 phosphorylation and also render any residual phosphorylation insensitive to rapamycin. By testing successively truncated polypeptides from the S6K1 tail, we found that both criteria are met by residues 393 to 398 (FIG. 4D). In addition, residues 399 to 402 and 403 to 410 likely contribute to FRB interactions, as their truncation progressively reduces phosphorylation (FIG. 17). N-terminal truncations, up to residue 381, have no significant effect.
[0264] Together, these data indicate that the FRB provides a secondary substrate- recruitment site near the entrance of the catalytic cleft. We presume that while the TOS and possibly other motifs are the primary means of substrate recruitment and specificity, the secondary site facilitates substrate entry into the otherwise restricted active site, and also provides an additional level of specificity.
[0265] A bi-partite substrate-recruitment mechanism is analogous to what has been proposed for the calcineurin phosphatase, the target of FK506-FKBP12. Most calcineurin substrates require both a primary and a secondary recruitment motif for efficient
dephosphorylation, and FK506FKBP12 inhibits by binding to the secondary recruitment motif site43. The secondary motif is rather degenerate, and its calcineurin affinity and importance vary substantially among different substrates44, and this too may be analogous in mTOR substrates.
FAT domain
[0266] The FAT domain contains 28 a helices arranged as a - a helical repeats. Helices l to a22 belong to the TPR repeat family and form three discontinuous domains (TRDl, TRD2 and TRD3). Helices a23 to a28 belong to the HEAT family and form a single domain (HRD). The four domains pack sequentially to form an a solenoid that is shaped like a C-clamp (FIG. 18A). TRDl, at the N-terminal tip of the clamp, interacts with the C lobe on one side of the kinase domain. After TRD2-TRD3 traverse to the other side of the kinase domain, the HRD at the C-terminal part of the clamp interacts with both the N and C lobes (FIG. 18B and FIG. 18C). [0267] Both the TRD1-KD and HRD-KD contacts involve residues highly conserved in mTOR orthologs, consistent with the two interfaces having an important role in the structure and function of mTOR. For example, a set of buried hydrogen bond contacts at the TRDl-KD interface (between Glul401 and Arg2317) and at the HRD-KD interface (Argl905-Glu2419, and Glnl941Gln2200) involve residues invariant in the 22 mTOR orthologs mentioned above (FIG. 18C).
[0268] The TRDl and HRD segments correspond to the FAT segments best conserved among PIKK family members28, suggesting that the FAT domain clamping onto the KD is a common feature of most PIKKs (FIG. 12). In addition, PBKs contain a helical repeat domain analogous to the HRD in its structure and interactions with the KD, although they lack the rest of the FAT domain (FIG. 18D). mLST8
[0269] mLST8 consists of seven WD40 repeats. At the narrow end of the mLST8 β propeller structure, a surface that extends across six WD40 repeats binds to both helices and intervening loop of the helix-loop-helix LBE. The interface involves mostly polar LBE residues and polar/aromatic mLST8 residues, and it is dominated by hydrogen bonds (FIG. 19).
[0270] mLST8 is thought to be a requisite activating subunit of mTOR complexes8'9. The structure suggests that the extended interaction surface of mLST8 may stabilize the helix-loop helix structure of the LBE directly, and the organization of the active site indirectly, through the LBE-FATC-catalytic loop spine of interactions discussed above (FIG. 13 A). In support, we note that lack of mLST8 results in the association of mTOR with heat shock proteins9, and we find that the solubility of overexpressed mTOR is highly dependent on mLST8 co-overexpression (not shown). These effects are unlikely to be caused by just two LBE hydrophobic residues (Met2271 and Met2281) that would be solvent exposed without mLST8 (FIG. 19B). In addition, the growth-suppression phenotype of a temperature-sensitive yeast Lst8 allele can be rescued by mutations45 either at the LBE hydrophobic core (A2290V) or at the following ka5 helix
(L2302Q), and the structure is consistent with these mutations stabilizing the local LBE structure. Control of mTOR kinase activity
[0271] The concept that active site restriction is a key aspect of mTOR regulation is supported by hyper-activating mutations45"47, most of which map to structural elements involved in limiting active site access. A large number of mutations cluster at the end of the catalytic cleft that is plugged by ka9b (FIG. 5 and FIG. 20). They map to the ka3, ka9, ka9b and kalO helices that pack extensively with each other, and to the FAT HRD portion that packs with ka3 and ka9. These mutations are likely to loosen the ka9b-centered structural framework that restricts access from this end of the cleft, presumably without destabilizing the entire active site structure. The role of the FAT clamp in stabilizing this structural framework is highlighted by the widely studied E2419K activating mutation, which eliminates the Glu2419-Argl905 salt bridge at the ka9-HRD interface (FIG. 18C and FIG. 20).
[0272] Two other mutations shown to increase TOR kinase activity map to a portion of the kal helix that is sandwiched between the FRB base and the N lobe β sheet45'46. These mutations (12017V and A2020V) are unlikely to unfold the FRB, because an FRB hydrophobic core mutation (W2027F) abolishes kinase activity40. The structure suggests that these mutations may loosen the rigid coupling of the FRB the catalytic cleft, increasing access to the active site.
[0273] A third cluster of mutations45 maps to the N-terminal portion of the FAT domain, to structural residues of the TRDl and of the TRDl -proximal portion of TRD2. They likely interfere with the ability of the FAT domain to clamp onto the C lobe of the kinase, with two possible effects. First, the HRD-KD interactions at the C-terminal end of the FAT solenoid may be indirectly destabilized, as the two FAT ends are structurally, and likely thermodynamically, coupled. Second, the disposition of the N-terminal mTOR segment and its associated RAPTOR, which likely further restrict active site access, could change or become more flexible relative to the KD.
Inhibitors of the ATP-bindins site [0274] To explore the determinants of inhibitor potency and specificity, we determined the structures of mTORAN-mLST8 bound to Torin2 and PP242, which are highly specific for mTOR, and to PI-103, which has dual specificity for mTOR and Class I PBKs (FIG. 9).
[0275] The overall orientation of Torin2 in the mTOR cleft is as predicted 48 (FIG. 6A and FIG. 21 A). The tricyclic benzonapththyridine ring binds to the adenine site and makes a hydrogen bond to the N-C lobe "hinge", analogous to one of two backbone hydrogen bonds made by ATP and diverse PI3/protein kinase inhibitors. The amino-pyridine group reaches into the "inner hydrophobic pocket", an area in the back of the cleft that many kinase inhibitors contact. However, it does not make the three predicted hydrogen bonds (to Asp2195, Asp2357 and Tyr2225)48. Rather, the structure reveals that a key interaction is the extensive stacking of the tricyclic benzonapththyridine ring with the indole group of Trp2239 from the "hinge" (FIG. 6A). In the ATPyS complex, Trp2239 stacks partially with a three-atom portion of the adenine. Torin2 takes full advantage of Trp2239, with a ten-atom portion of its tricyclic ring stacking with the indole group. This likely makes a substantial contribution to the sub-nanomolar potency48 of Torin2. In addition, because Trp2239 is not present in canonical protein kinases or in PBKs, it would also contribute to Torin2's ~800-fold specificity for mTOR over PBKs48. The structure also reveals the packing of the Torin2 trifluoromethyl group packs into an N lobe pocket (Ile2163, Pro2169 and Leu2185; FIG. 6A). These contacts are less extensive than those made to Trp2239, and only Leu2185 is variable across the PIKK and PBK families. However, this portion of the N lobe β sheet exhibits considerable variation in its relative orientation in PBK structures, and it may thus contribute to Torin2-mTOR specificity.
[0276] PP242 consists of the adenine -mimetic pyrazolopyrimidine scaffold common to
PB/tyrosine kinase inhibitors, with a hydroxyindole substituent at a position that often points to the inner hydrophobic pocket49. In mTOR, this pocket is lined with residues conserved across the PBK and PIKK families, and the selectivity of PP242 for mTOR was unexpected49. The structure reveals that while these two PP242 groups are generally positioned as predicted49, mTOR undergoes a conformational change that expands and deepens its inner hydrophobic pocket, with the hydroxyindole group reaching deep into the new space (FIG. 6B and FIG. 2 IB). This involves the side chain of Tyr2225 at the back of the pocket swinging (Δχι = 108°) out of the way of the hydroxyindole group (FIG. 6C and FIG. 21C). Because Tyr2225 is part of the local hydrophobic core between the N and C lobes, this necessitates additional concerted changes. The Leu2354 side chain rotates (Δχι = 166°) out of the way of Tyr2225, the Gln2223 side chain moves in to plug a resulting gap, and a 3-residue backbone stretch (residues 2223 to 2225) shifts by ~1 A. In PBKs, Leu2354 is replaced by a conserve phenylalanine that cannot undergo a similar conformational change without an even more extensive repacking of the local hydrophobic core. Leu2354 is thus likely to be a major, though indirect, determinant of the selectivity of PP242 for mTOR over PBKs and other kinases.
[0277] The multi-targeted PI-10350 does not take advantage of any of the aforementioned mTORspecific features. The morpholine ring binds to the adenine pocket and makes two hydrogen bonds to the "hinge", while the m-phenol group binds to the inner pocket and makes two hydrogen bonds to the Tyr2225 and Asp2195 side chains at the back of the cleft (FIG. 6D and FIG. 21D). These hydrogen bonds are likely to be important for the high affinity of PI-103 for mTOR and, presumably, for Class I PBKs where the relevant protein groups are similarly positioned. In support, we note that the ~500-fold weaker affinity50 Class III PBK-PI-103 complex lacks both m-phenol hydrogen bonds and one of the "hinge" hydrogen bonds32.
Discussion
[0278] The mTORAN structure reveals an intrinsically active but otherwise highly restricted catalytic centre, pointing to substrate recruitment as a major mechanism controlling the kinase activity. Our data indicate that in addition to a primary recruitment motif, a secondary recruitment motif proximal to the substrate phosphorylation site is needed for efficient phosphorylation. The FRB acts as a gatekeeper by preventing inappropriate access to the active site, while also granting privileged substrates access by providing a binding site for the secondary motif.

Methods Summary
Protein expression and purification
[0317] The boundary of the crystallized human mTORAN (residues 1376-2549) was identified by screening successive N-terminal truncations of mTOR, produced by transient transfection in HEK293-F cells, for expression levels, solubility and size exclusion
chromatography profile (not shown). For large-scale production of mTORAN-mLST8, we generated an HEK 293 -F cell line that was stably-transfected sequentially by modified pcDNA3.1 vectors encoding FLAG-tagged mLST8 and FLAG-tagged mTORAN. In the absence of mLST8 co-expression, the level of soluble mTORAN was substantially lower, and it co- purified with endogenous mLST8 (not shown). The mTOR -mLST8, full-length human mTORmLST8 and human mTORCl (mTOR-mLST8 -RAPTOR) complexes were similarly produced in HEK 293 -F cell lines that were stably transfected with the FLAG-tagged versions of the proteins. Cells were grown as monolayers in 15 centimeter plates. They were lysed in 50mM Tris-Cl, pH 8.0, 100 mM KC1, 400 mM NaCl, 1 mM EDTA, 1 mM EGTA, 10 % (v/v) glycerol, 2 mM dithiothreitol (DTT) and protease inhibitors using French Press. After centrifugation, the FLAG-tagged proteins were affinity purified using anti-FLAG M2 agarose beads (Sigma). Following cleavage of the FLAG-tags by tobacco etch virus (TEV) protease, they were purified by ion exchange (MonoQ) and gel-filtration chromatography. The purified complex was concentrated to 5 mg ml-1 by ultrafiltration in 20 mM Tris-Cl, 500 mM NaCl, 10 mM DTT, pH 8.0 and was used for crystallization immediately. For kinase assays, 10% (v/v) glycerol was added to protein aliquots for storage at -80 °C.
[0318] Human S6Kl IIkl protein, which contains the kinase-inactivating K100R mutation, was produced by infecting High Five insect cells with a pFastBacl baculovirus expressing the FLAG-tagged protein. It was purified by affinity chromatography with anti-FLAG M2 agarose beads. The protein was concentrated to 8 mg ml"1 in 50 mM Tris-Cl, 400 mM NaCl, ImM EDTA, ImM EGTA, 5% (v/v) glycerol, 10 mM DTT, 1 mM Pefabloc, pH 8.0, and it was stored at -80 °C.
[0319] Human 4EBP1 was overexpressed in the E. coli strain BL21(DE3) from a modified pGEX4T3 vector, and was purified by glutathione affinity chromatography, cleavage of the GST tag with TEV protease, fractionation on MonoQ column, removal of free GST by glutathione affinity, and finally gel filtration (Superdex75) chromatography. The peak fractions were concentrated to 20 mg ml"1 in 20 mM Tris-Cl, 200 mM NaCl, 5% (v/v) glycerol, 10 mM DTT, pH 8.0.
[0320] The mutant and wild type (for direct comparison in FIG. 13) mTOR complexes were produced by transiently trans fecting 293 -F cells with modified pcDNA 3.1 (+) vectors encoding FLAG-tagged wild type, D2338A or H2340A mTORAN and untagged mLST8. After two days, the cells were harvested and the proteins were purified using anti-FLAG M2 agarose beads as described above. After extensive washing of the beads, proteins were eluted with 0.1 mg ml-1 FLAG peptide in 20 mM Tris-HCl, pH 8.0, 400 mM NaCl, 2 mM DTT, 10% glycerol, and concentrated. Protein concentrations were determined by A2go and confirmed by
immunoblotting with anti-FLAG antibody.
Crystallization and data collection
[0321] Crystals were grown by the hanging-drop vapour diffusion method at 4 °C. Apo- crystals of the mTORAN-mLST8 complex were grown from 100 mM Tris-Cl, 6-8% (w/v) polyethylene glycol (PEG) 8000, 500 mM NaCl, 10% (v/v) glycerol, 10 mM DTT, pH 8.5. Crystals of the mTORAN-mLST8 bound to ADP-MgF3-Mg2 were grown similarly, except the well-buffer contained 10 mM MgCl2, 3 mM ADP, and 20 mM NaF. The mTORAN- mLST8ATPyS-Mg2 complex was prepared by soaking apo-crystals for one hour in a stabilization buffer of 50 mM Tris-Cl, pH 8.5, 10 mM Tris-Cl, 8.0, 10% PEG8000, 0.1 M NaCl, 6% glycerol, supplemented with 5 mM MgCl2 and 1 mM ATPyS. The mTORAN-mL ST 8 - AMPPNP-Mn2 complex was prepared by soaking apo-crystals similarly, except the stabilization buffer had a pH of 7.5 and it was supplemented with 1 mM AMPPNP and 2 mM MnCl2, and the data was collected at the Manganese absorption edge. Crystals of mTORAN-mLST8-Torin2 and mTORAN- mLST8-PI-103 were prepared by mixing 1 mM of the inhibitors with the protein. Co-crystals appeared from the same condition as the apo-crystals. Crystals of mTORAN-mLST8-PP242 were prepared by soaking apo-crystals for 2.5 hours in the stabilization buffer supplemented with 0.2 mM PP242. Apo-crystals were harvested in stabilization buffer, transferred to 50 mM Tris-Cl, pH 8.5, 10 mM Tris-Cl, pH 8.0, 0.1 M NaCl, 14% (w/v) PEG8000, 22% (v/v) glycerol, and were flash-frozen in liquid nitrogen. Crystals with ADP-MgF3-Mg2, ATPyS-Mg2, Torin2, PI- 103 and PP242 were flash- frozen similarly, except for the presence of the corresponding cofactors or inhibitors (0.1 mM) in the buffers. Diffraction data were collected at -170 °C at the ID24C and ID24E beamlines of the Advanced Photon Source, and they were processed with the HKL suite51.
Structure determination and refinement [0322] Initial phases were obtained from isomorphous and anomalous differences of two heavy atom derivatives, prepared by soaking crystals in stabilization buffer lacking DTT and supplemented with 1 mM uranyl acetate (1 hour), or with 0.4 mM potassium-gold cyanide (75 min.) at 4 ° C. Initial phases, calculated with the program SHARP52 had a mean figure of merit of 0.35 (35.0 to 4.5 A). The uranyl derivative had a dispersive phasing power (Pp) of 0.89 and anomalous Pp of 0.60, with a dispersive Rcums of 0.79 and anomalous Rcums of 0.95. The gold derivative had a dispersive Pp of 0.80 and anomalous Pp of 0.29, with a dispersive Rcums of 0.66 and anomalous Rcums of 0.98. The phases were improved using solvent flattening and two-fold ncs averaging with multiple masks with the program DM53. The model was built using O54 and refined first with REFMAC553 and then with PHENIX55, using tight ncs restraints on atom positions. The final model contains residues 1385 to 2549 of human mTOR, and 8 to 324 of human mLST8- mTORAN residues 1376-1384 at the N-terminus, residues 1815-1866 in the FAT domain, and residues 2437-2491 between ka9b and kalO in the KD are disordered. mLST8 residues 1-7 and 325-326 from the N- and C-termini are disordered. The Ramachandran plot, calculated by PROCHECK, has 88.5, 11.0 and 0.5 % of the residues in the most favored, additionally allowed, and generously allowed regions, respectively. There are no residues in disallowed regions. The Rfree test set of the Native data contains 1699 reflections.
In vitro kinase assays
[0323] All kinase assays were performed in a buffer of 25 mM HEPES, pH 7.4, 100 mM
NaCl, 10 mM MgC12, 2 mM DTT, 3 % (v/v) glycerol, for 30 minutes at 30 ° C, in a final volume of 15 μΐ. For a typical reaction, the indicated amount of enzymes, substrates, and competitors were incubated together for 10 minutes on ice in the kinase buffer in a final volume of 13.5 μΐ. Reactions were started by the addition of 1.5 μΐ of cold ATP (0.5 mM final concentration) including 2 μ& of [γ-32Ρ] ATP (6000 Ci/mmol, Perkin-Elmer). In assays with rapamycin, all reactions in a titration contained a constant level of 3.3 % DMSO. Reactions were stopped by the addition of 15 μΐ of 2X NuPAGE LDS sample buffer and boiling for 3 minutes, and were resolved in a 4-12 % NuPAGE Bis-Tris gel. Where applicable, each reaction was split into two for analysis by phosphorimaging and immunoblotting. All antibodies were obtained from Cell Signaling, except for the anti-FLAG antibody which was obtained from Sigma.
Example 2: In vitro assay for screening activity of mTOR modulators
Primary Screening Assay
[0324] Cancer stem cells (i.e. tumor-initating cells) are isolated as previous described56"59 and cultured as speheres in serum-free cell media. Screening methodologies are known6 in the art are performed as follows. Cancer stem cells are dissociated into single cells and seeded at 3,000 cells per well in 100 uL medium in 96-well plates. mTOR modulator compounds are dissolved in DMSo, re-aliquoted in daughter plates as 1 and 0.2 mmol/L solutions, and added using a pin tool to achieve final concentrations of 1 or 0.2 umol/L. mTOR modulator effects are compared with cells optimally proliferating in 0.1% DMSO alone, whereas wells filled with media served as the background. alamarBlue (10 uL) is added after 72 hours to evaluate cellular health, and fluorescence intensity is measured after 24 hours on a microplate reader equipped with a λ54ο excitationA,59o emission filter. Hits are defined as compounds that cause a signal decrease of at least 45% as compared with controls. Confirmatory tests are performed using 8- point, 3-fold serial dilutions of mTOR modulators. Cells are seeded, treated with serially diluted mTOR modulators, and test for alamar Blue reduction.
Sphere Formation Assay
[0325] Cancer stem cells are seeded in triplicate in untreated 96-well plates at a density of 3,000 cells per well in 50 uL per wll, containing 30% SKP condition media. mTOR modulators are diluted in medium (1 : 1000) and immediately added to the cells in a volume of 50 uL (final concentration of DMS 0.05%>). Cells are retreated 72 hours postplating with drugs and fixed after 6 days with 4% paraformaldehyde. Sphere number is determined by manual counting, and the results are expreesed as the mean sphere number of treated wells as compared with DMSO-treated wells x 100.
Kinase Assay
[0326] Cancer stem cells are dissociated into single cells and treated in the presence of
0.1% DMSO or 100 nol/L of mTOR modulator for 3 hours. Cells are solubilized in NP-40 lysis buffer, the lysates normalized for protein content, and then incubated with mTOR monoclonal antibody. Immune complexes are recovered with protein A-Sepharose beads and incubated with 5 μα of [γ-32Ρ] ATP (6000 Ci/mmol, Perkin-Elmer) at 30 ° C for 20 minutes and 10 ug of dephosphorylated 4EBP1 in 30 uL of mTOR kinase buffer (25 mM HEPES, pH 7.4, 100 mM NaCl, 10 mM MgC12, 2 mM DTT, 3 % (v/v) glycerol). The reactions are stopped by adding 20 uL of Laemmli buffer. Samples are separated by SDS-PAGE, and gells are visualized by autoradiography.
Example 3: Xenograft assay for mTOR modulator toxicity
[0327] Cancer stem cells are resuspended in PBS, mixed 1 :3 with Matrigel and injected in 30-uL volume into the dermis of 4-5 week old NOD/SCID (nonobese diabetic/severe combined immunodeficient) mice. mTOR modulator treatment begins when tumor size reaches approximately 50 to 100 mm3. Mice are injected intravenously on 2 consecutive days each week with either mTOR modulator or vehicle for a total of 2 to 3 cycles. Blood samples are collected 24 hours after the last mTOR modulator dose and analyzed to determine the differences blood cell/white blood cell counts.
