Variant
" variant " refers to different from reference nucleic acid or polypeptide but retains polypeptide or the nucleic acid of its intrinsic propesties.Usually, variant and reference nucleic acid or polypeptide closely similar on the whole and identical in many regions.
When for this paper, " variant " refers to that sequence is different from therapeutic protein (for example, see " therapeutic " of table 1 arranges), albumin protein and/or albumin fusion proteins respectively but retains its other local that describe or that other approach of this area is known at least one function and/or the Therapeutic protein moiety of albumin fusion proteins of the present invention for the treatment of characteristic, the albumin part of albumin fusion proteins of the present invention or albumin fusion proteins of the present invention herein.Usually, variant with correspond to albumin fusion proteins Therapeutic protein moiety therapeutic protein, corresponding to the albumin protein of the albumin protein portion of albumin fusion proteins and/or the aminoacid sequence of albumin fusion proteins closely similar on the whole and identical with it in many regions.The nucleic acid of these variants of coding is also contained in the present invention.
The invention still further relates to therapeutic protein (the such as aminoacid sequence of the X of therapeutic protein disclosed in table 1 comprised with the Therapeutic protein moiety such as corresponding to albumin fusion proteins of the present invention; Or the aminoacid sequence of the Therapeutic protein moiety of the albumin fusion proteins of being encoded by the polynucleotide described in table 1 and table 2 or albumin fusion construct; Or its fragment or variant), corresponding to the albumin protein (aminoacid sequence of the albumin protein portion of the albumin fusion proteins of such as being encoded by the polynucleotide described in table 1 and table 2 or albumin fusion construct of the albumin protein portion of albumin fusion proteins of the present invention; The aminoacid sequence shown in SEQ ID NO:1; Or the aminoacid sequence of its fragment or variant) and/or the aminoacid sequence of albumin fusion proteins have at least 80%, 85%, 90%, 95%, 96%, 97%, 98%, 99% or 100% homogeneity aminoacid sequence or consisting of protein.Additionally provide the fragment (such as fragment described herein) of these polypeptide.The present invention also comprises the polypeptide by such polynucleotide encoding, described polynucleotide under stringent hybridisation conditions (such as at about 45 degrees Celsius, with the membrane-bound DNA hybridization of filter in 6X sodium chloride/sodium citrate (SSC), then at about 50-65 degree Celsius, at 0.2X SSC, one or many is washed) in 0.1%SDS, (such as at about 45 degrees Celsius under high stringent condition, with the membrane-bound DNA hybridization of filter in 6X sodium chloride/sodium citrate (SSC), then at about 68 degrees Celsius, at 0.1X SSC, one or many is washed) in 0.2%SDS, or (for example, see Ausubel under other stringent hybridisation conditions that those skilled in the art will know that, F.M. people is waited, compile, 1989, " Current protocol in MolecularBiology ", Green publishing associates, and John Wiley & Sons Inc. Inc., NewYork, 6.3.1-6.3.6 and 2.10.3) under hybridize with the complementary strand of nucleic acid molecules of coding albumin fusion proteins of the present invention.The polynucleotide of these polypeptide of coding are also contained in the present invention.
Have the polypeptide with inquiry aminoacid sequence with the aminoacid sequence of at least such as 95% " homogeneity " and refer to that the aminoacid sequence of desired polypeptides is identical with search sequence, just desired polypeptides sequence can comprise nearly five amino acid change in every 100 aminoacid of inquiry aminoacid sequence.In other words, obtain to have, with inquiry aminoacid sequence, there is the polypeptide of the aminoacid sequence of at least 95% homogeneity, can insert, delete or with in another kind of amino acid replacement aim sequence nearly 5% amino acid residue.These changes of reference sequences can occur in amino or the carboxy terminal positions of reference amino acid sequence, or, between the residue that individually can be dispersed in reference sequences or in the one or more adjacent groups being dispersed in reference sequences. between those terminal positions Anywhere
In fact, known computer program can be utilized to determine as usual, and whether the aminoacid sequence of any specific polypeptide and albumin fusion proteins of the present invention or its fragment (Therapeutic protein moiety of such as albumin fusion proteins or the albumin part of albumin fusion proteins) has the homogeneity of at least 80%, 85%, 90%, 95%, 96%, 97%, 98% or 99%.Utilize with the people such as Brutlag (Comp.App.Biosci.6:237-245,1990) the FASTDB computer program based on algorithm can determine the method for optimizing that mensuration search sequence (sequence of the present invention) is mated with the best overall between aim sequence, also referred to as global sequence's comparison.In sequence alignment, inquiry and aim sequence can be all nucleotide sequences or be all aminoacid sequence.The result of described global sequence comparison represents with homogeneity percentage ratio.Preferred parameter for FASTDB amino acid alignment is: matrix=PAM0, k-tuple=2, Mismatch Penalty=1, connect point penalty=20, randomization group leader=0, cut-off score=1, window size=sequence length, Gap Penalty=5, breach size point penalty=0.05, the shorter one in the length of window size=500 or object aminoacid sequence.
If aim sequence deletes because of N-or C-end but not inner deletion is shorter than search sequence, so manually must revise result.This is because FASTDB program can not consider N-and the C-end truncate of aim sequence when calculating overall homogeneity percentage ratio.For relative to the aim sequence of search sequence in the truncate of N-and C-end, following correction homogeneity percentage ratio, calculate in search sequence be positioned at aim sequence N-and C-end, do not mate/the number of residues of comparison with corresponding aim sequence, as the percentage ratio of search sequence base sum.Whether residue mate/and comparison is determined by the result of FASTDB sequence alignment.Then deduct this percentage ratio from the homogeneity percentage ratio utilizing special parameter to calculate by above-mentioned FASTDB program, draw final homogeneity percentage score.This final homogeneity percentage score is exactly for score of the present invention.Only consider to be positioned at N-and the C-end of aim sequence during artificial adjustment homogeneity percentage score, do not mate with search sequence/the residue of comparison.That is, the inquiry residue residue of aim sequence farthest beyond N-and C-terminal residue is only considered to be positioned at.
Such as, the search sequence of the aim sequence of 90 amino acid residues and 100 residues is compared to measure homogeneity percentage ratio.Delete the N-end occurring in aim sequence, therefore FASTDB comparison does not show the coupling/comparison result of initial 10 residues of N-end.10 unpaired residues account for 10% (total number of residues of the unmatched residue number/search sequence of N-and C-end) of sequence, therefore from the homogeneity percentage score drawn by FASTDB program computation, deduct 10%.If remaining 90 residues mate completely, then final homogeneity percentage ratio will be 90%.In another example, the search sequence of the aim sequence of 90 residues and 100 residues is compared.Current deletion is inner deletion, and therefore N-or the C-end of aim sequence does not have not mate with search sequence/the residue of comparison.In this case, the homogeneity percentage ratio calculated by FASTDB is without the need to carrying out manual correction.Again declare, only have be positioned at aim sequence according to the display of FASTDB comparison N-and C-end beyond, do not mate with search sequence/the resi-dues needs of comparison are manual to be corrected.Do not carry out the artificial correction of other form in the present invention.
The variant usually normal HA identical with it with length or therapeutic protein has the sequence iden of at least 75% (preferably at least about 80%, 90%, 95% or 99%).Utilize revise in order to sequence similarity search program blastp, blastn, blastx, tblastn and tblastx (people such as Karlin, Proc.Natl.

Evol. 36:290-300,1993, completely to be incorporated herein by reference) algorithm that adopts, the homology or homogeneity that measure nucleotide or amino acid sequence level is analyzed by BLAST (Basic LocalAlignment Search Tool and basic Local Alignment Search Tool).
First the method that blast program utilizes considers the analogous segment between search sequence and database sequence, then to all coupling assessment significance,statisticals that qualification draws, finally only sums up the coupling that those meet predetermined significance threshold value.About the discussion of the basic problem in the similarity searching of sequence library, see people such as Altschul, Nature Genetics 6:119-129,1994, it is completely incorporated herein by reference.The search parameter of rectangular histogram, description, comparison, expected value (namely reporting the significance,statistical threshold value of the sequence of the pairing for database sequence), cutoff, matrix and filter all adopts default setting.The default scoring matrix that blastp, blastx, tblastn and tblastx adopt is BLOSUM62 matrix (people such as Henikoff, Proc. Natl. Acad. Sci. USA 89:10915-10919 1992, to be completely incorporated herein by reference).For blastn, by the ratio of M (prize of namely mating residue divides) and N (not mating the point penalty of residue) to arrange rating matrix, wherein the default value of M and N is 5 and-4 respectively.Four blastn parameter: Q=10 (gap opening penalty) can be adjusted as follows; R=10 (gap extension penalty); Wink=1 is (along search sequence at each wink thposition produces word hits); Gapw=16 (setting window width wherein produces containing breach comparison).Equal blastp optimum configurations is Q=9; R=2; Wink=1 and gapw=32.The DNA parameter that between the sequence that can obtain from GCG software kit version 10.0, comparison program Bestfit uses is GAP=50 (gap opening penalty) and LEN=3 (gap extension penalty), and protein compares is set to GAP=8 and LEN=2 on an equal basis.

Natural exist variant and be called " allele variant ", one of several replaceable form referring to the gene occupying given locus on organism chromosome (Genesll, Lewin, B. compile, John Wiley & Sons, New York, 1985).These allele variants can polynucleotide and/or peptide level different, and to comprise in the present invention.Or, the variant of non-natural existence is prepared by induced-mutation technique or Direct synthesis technique.
Utilize known protein engineering and the method for recombinant DNA technology, variant can be produced to improve or to change the feature of polypeptide of the present invention.Such as, can one or more aminoacid be deleted from the N-end of polypeptide of the present invention or C-end and do not cause the substantial loss of biological function.Such as, the people such as Ron (J.Biol.Chem.268:2984-2988,1993) report the variant KGF protein even still after deletion 3,8 or 27 amino terminal amino acid residues with heparin binding activity.Similarly, IFN-γ shows higher activity people such as (, J.Biotechnology 7:199-216,1988) Dobeli reaching ten times after the carboxyl terminal of from then on protein deletes 8-10 amino acid residue.
And have sufficient evidence to prove, variant usually can retain and there is the similar biologic activity of protein to natural.Such as, Gayle and colleague (J.Biol.Chem.268:22105-22111,1993) thereof have carried out mutation analysis widely to human cell factor IL-1a.They utilize random mutagenesis to create more than 3,500 kinds of unique IL-1a mutants, and namely in the total length of molecule, often kind of variant on average has 2.5 amino acid changes.At each possible amino acid position, various mutations is checked.Research worker finds " most molecule can be very little on [combining or biologic activity] impact while being changed ".In fact, check more than 3, in 500 kinds of nucleotide sequences, only have 23 kinds of unique amino acid sequences to create the active protein significantly different from wild type.
And, even if delete from the N-end of polypeptide or C-end modification or the forfeiture that one or more aminoacid can cause one or more biological functions, but still other biologic activity can be retained.Such as, when being less than most residue of secreted form from N-end or the removing of C-end, the ability of deleting variant induction by likely retaining and/or combining the antibody identifying secreted form.The conventional method known by described herein and other approach of this area can be easy to determine whether the shortage N-end of protein or the specific polypeptide of C-terminal residue remain this immunogenic activity.
Therefore, the present invention also comprises the polypeptide variants with functional activity (such as biologic activity and/or therapeutic activity).In one embodiment, the invention provides the albumin fusion proteins variant with the functional activity (such as biologic activity and/or therapeutic activity) corresponding with one or more biologys of therapeutic protein and/or therapeutic activity, wherein therapeutic protein corresponds to the Therapeutic protein moiety of albumin fusion proteins.In another embodiment, the invention provides the albumin fusion proteins variant with the functional activity (such as biologic activity/or therapeutic activity) corresponding with one or more biologys of therapeutic protein and/or therapeutic activity, wherein therapeutic protein corresponds to the Therapeutic protein moiety of albumin fusion proteins.This variant comprises the deletion very little to activity influence, insertion, inversion, the repetition selected according to general rule known in the art and substitutes.The polynucleotide of this variant of encoding also are contained in the present invention.

The first strategy make use of the toleration of the amino acid replacement of natural selection in evolutionary process.Conserved amino acid can be identified by the aminoacid sequence comparing different plant species.These conserved amino acids may be important to the function of protein.On the contrary, the amino acid position of replacement that natural selection has tolerated shows that these positions are not vital to protein function.Therefore, the position that tolerant of amino acid substitutes can be modified, still keep the biologic activity of this protein simultaneously.
The second strategy utilizes genetic engineering to introduce aminoacid change, to identify the vital region of protein function at the ad-hoc location of clone gene.Such as, direct mutagenesis or alanine scanning mutagenesis (each residue place in the molecule introduces single alanine mutation) can be used.See Cunningham and Wells, Science 244:1081-1085,1989.Then the biologic activity of the mutating molecule so produced can be tested.
As the author said, these two kinds of strategies disclosed the surprising tolerant of amino acid of albumen mass-energy substitute.Author also indicates which aminoacid change is that in protein, some amino acid position is likely allowed.Such as, the amino acid residue that great majority bury (in the tertiary structure of protein) needs non-polar sidechain, and little characteristic of surface side chains is normally guarded.And the conserved amino acid of tolerance substitutes the replacement relating to aliphatic or hydrophobic amino acid Ala, Val, Leu and Ile; The replacement of OH residues Ser and Thr; The replacement of acidic residues Asp and Glu; The replacement of amide residues Asn and Gln; The replacement of alkaline residue Lys, Arg and His; The replacement of aromatic residue Phe, Tyr and Trp; And the replacement of small-sized aminoacid Ala, Ser, Thr, Met and Gly.Except conserved amino acid substitutes, variant of the present invention comprises (i) polypeptide mentioned containing one or more nonconserved amino acid residues, the amino acid residue wherein substituted can be encoded by genetic code in yes or no, or (ii) is containing one or more polypeptide substituted with substituent amino acid residue, or (iii) has such as improved polypeptide stability and/or dissolubility compound (such as Polyethylene Glycol) with another compound merges or chemically conjugated polypeptide, or (iv) polypeptide containing other aminoacid such as such as IgG Fc district fusogenic peptide.According to instruction herein, think that this variant polypeptide is within the scope of those skilled in the art.
Such as, the polypeptide variants containing the amino acid replacement of other electrically charged or neutral amino acid alternative belt charge amino acid useful can produce the protein with improved characteristics, such as assembles less.The gathering of pharmaceutical formulations not only reduces activity, but also improves the removing because the immunogenicity of aggregation causes.See people such as Pinckard, Clin.Exp.Immunol.2:331-340,1967; The people such as Robbins, Diabetes 36:838-845,1987; The people such as Cleland, Crit.

The structure of embodiment 24:GAS reporter molecule construction
A kind of signal transduction pathway relating to cell differentiation and propagation is called Jaks-STAT approach.The protein bound γ activated in Jaks-STAT approach activates site " GAS " element or interferon-sensitive response element (" ISRE "), and they are arranged in polygenic promoter perhaps.The expression of the Binding change related gene of protein and these elements.
GAS and ISRE element is subject to the identification of the class transcription factor being called signal transducer and transcriptional activator or " STAT ".There are six members in STAT family.Stat1 and Stat3 is present in many cell types, and Stat2 is (as being general to the response of IFN-α) too.Stat4 is more limited, and does not exist in many cell types, although it was at I class t helper cell, found with in the cell after IL-12 process.Stat5 is called the mammoplasia factor at first, but has been found that it is present in other cell with higher concentration, comprises medullary cell.It can be subject to the activation of many cytokines in tissue culture cells.
STAT because being called one group of kinase whose tyrosine phosphorylation of Janus kinases (" Jaks ") family to be activated from Chromosome migration to core.Jaks represents a unique class of solubility tyrosine kinase, comprises Tyk2, Jak1, Jak2 and Jak3.These kinases show significant sequence similarity, and catalytically inactive in resting cell usually.
Jaks is subject to the activation of the multiple receptor that following table is summed up.(adapting the summary from Schidler and Darnell, Ann.Rev.Biochem.64:621-51,1995).The cytokine receptor family that can activate Jaks is divided into two groups: (a) 1 class comprise the receptor of IL-2, IL-3, IL-4, IL-6, IL-7, IL-9, IL-11, IL-12, IL-IS, Epo, PRL, GH, G-CSF, GM-CSF, LIF, CNTF and thrombopoietin; (b) 2 classes comprise IFN-a, IFN-g and IL-10.1 receptoroid has a conserved cysteine motifs (one group of 4 Conserved cysteines and 1 tryptophan) and WSXWS motif (the nearly center of film of coding Trp-Ser-Xaa-Trp-Ser (SEQ ID NO:53))
Therefore, after part and receptors bind, Jaks is activated, and it activates STAT then, and it shifts and subsequently in conjunction with GAS element.This whole process is included in Jaks-STAT signal transduction pathway.Therefore, the activation of the Jaks-STAT approach reflected by the combination of GAS or ISRE element can be used for indicating the protein relating to cell proliferation and differentiation.Such as, known somatomedin and cytokine activation Jaks-STAT approach (see below table 5).Therefore, by using the GAS element be connected with acceptor molecule, the activity factor of Jaks-STAT approach can be identified.
