Definitions

  • This invention relates to newly identified polynucleotides, polypeptides encoded by these polynucleotides, antibodies that bind these polypeptides, uses of such polynucleotides, polypeptides, and antibodies, and their production.
  • sorting signals are amino acid motifs located within the protein, to target proteins to particular cellular organelles.
  • One type of sorting signal called a signal sequence, a signal peptide, or a leader sequence, directs a class of proteins to an organelle called the endoplasmic reticulum (ER).
  • ER endoplasmic reticulum
  • both groups of proteins can be further directed to another organelle called the Golgi apparatus.
  • the Golgi distributes the proteins to vesicles, including secretory vesicles, the cell membrane, lysosomes, and the other organelles.
  • Proteins targeted to the ER by a signal sequence can be released into the extracellular space as a secreted protein.
  • vesicles containing secreted proteins can fuse with the cell membrane and release their contents into the extracellular space - a process called exocytosis. Exocytosis can occur constitutively or after receipt of a triggering signal. In the latter case, the proteins are stored in secretory vesicles (or secretory granules) until exocytosis is triggered.
  • proteins residing on the cell membrane can also be secreted into the extracellular space by proteolytic cleavage ofa "linker" holding the protein to the membrane.
  • the present invention relates to novel polynucleotides and the encoded polypeptides. Moreover, the present invention relates to vectors, host cells, antibodies, and recombinant and synthetic methods for producing the polypeptides and polynucleotides. Also provided are diagnostic methods for detecting diseases, disorders, and/or conditions related to the polypeptides and polynucleotides, and therapeutic methods for treating such diseases, disorders, and/or conditions. The invention further relates to screening methods for identifying binding partners ofthe polypeptides.
  • isolated refers to material removed from its original environment (e.g., the natural environment if it is naturally occurring), and thus is altered “by the hand of man” from its natural state.
  • an isolated polynucleotide could be part of a vector or a composition of matter, or could be contained within a cell, and still be “isolated” because that vector, composition of matter, or particular cell is not the original environment ofthe polynucleotide.
  • isolated does not refer to genomic or cD ⁇ A libraries, whole cell total or mR ⁇ A preparations, genomic D ⁇ A preparations (including those separated by electrophoresis and transferred onto blots), sheared whole cell genomic D ⁇ A preparations or other compositions where the art demonstrates no distinguishing features ofthe polynucleotide/sequences ofthe present invention.
  • a "secreted" protein refers to those proteins capable of being directed to the ER, secretory vesicles, or the extracellular space as a result of a signal sequence, as well as those proteins released into the extracellular space without necessarily containing a signal sequence. If the secreted protein is released into the extracellular space, the secreted protein can undergo extracellular processing to produce a "mature" protein. Release into the extracellular space can occur by many mechanisms, including exocytosis and proteolytic cleavage.
  • the polynucleotides ofthe invention are at least 15, at least 30, at least 50, at least 100, at least 125, at least 500, or at least 1000 continuous nucleotides but are less than or equal to 300 kb, 200 kb, 100 kb, 50 kb, 15 kb, 10 kb, 7.5 kb, 5 kb, 2.5 kb, 2.0 kb, or 1 kb, in length.
  • polynucleotides ofthe invention comprise a portion ofthe coding sequences, as disclosed herein, but do not comprise all or a portion of any intron.
  • the polynucleotides comprising coding sequences do not contain coding sequences of a genomic flanking gene (i.e., 5' or 3' to the gene of interest in the genome). In other embodiments, the polynucleotides ofthe invention do not contain the coding sequence of more than 1000, 500, 250, 100, 50, 25, 20, 15, 10, 5, 4, 3, 2, or 1 genomic flanking gene(s).
  • a "polynucleotide” refers to a molecule having a nucleic acid sequence contained in SEQ ID NO:X or the cDNA contained within the clone deposited with the ATCC.
  • the polynucleotide can contain the nucleotide sequence ofthe full length cDNA sequence, including the 5' and 3' untranslated sequences, the coding region, with or without the signal sequence, the secreted protein coding region, as well as fragments, epitopes, domains, and variants ofthe nucleic acid sequence.
  • a "polypeptide” refers to a molecule having the translated amino acid sequence generated from the polynucleotide as broadly defined.
  • the full length sequence identified as SEQ ID NO:X was often generated by overlapping sequences contained in multiple clones (contig analysis).
  • a representative clone containing all or most ofthe sequence for SEQ ID NO:X was deposited with the American Type Culture Collection ("ATCC"). As shown in Table 1, each clone is identified by a cDNA Clone ID (Identifier) and the ATCC Deposit Number.
  • the ATCC is located at 10801 University Boulevard, Manassas, Virginia 20110-2209, USA.
  • the ATCC deposit was made pursuant to the terms ofthe Budapest Treaty on the international recognition ofthe deposit of microorganisms for purposes of patent procedure.
  • a “polynucleotide” ofthe present invention also includes those polynucleotides capable of hybridizing, under stringent hybridization conditions, to sequences contained in SEQ ID NO:X, the complement thereof, or the cDNA within the clone deposited with the ATCC.
  • Stringent hybridization conditions refers to an overnight incubation at 42 degree C in a solution comprising 50% formamide, 5x SSC (750 mM NaCl, 75 mM trisodium citrate), 50 mM sodium phosphate (pH 7.6), 5x Denhardt's solution, 10% dextran sulfate, and 20 ⁇ g/ml denatured, sheared salmon sperm DNA, followed by washing the filters in 0.
  • nucleic acid molecules that hybridize to the polynucleotides ofthe present invention at lower stringency hybridization conditions. Changes in the stringency of hybridization and signal detection are primarily accomplished through the manipulation of formamide concentration (lower percentages of formamide result in lowered stringency); salt conditions, or temperature.
  • washes performed following stringent hybridization can be done at higher salt concentrations (e.g. 5X SSC).
  • blocking reagents include Denhardt's reagent, BLOTTO, heparin, denatured salmon sperm DNA, and commercially available proprietary formulations.
  • the inclusion of specific blocking reagents may require modification ofthe hybridization conditions described above, due to problems with compatibility.
  • polynucleotide which hybridizes only to polyA+ sequences (such as any 3' terminal polyA+ tract of a cDNA shown in the sequence listing), or to a complementary stretch of T (or U) residues, would not be included in the definition of "polynucleotide,” since such a polynucleotide would hybridize to any nucleic acid molecule containing a poly (A) stretch or the complement thereof (e.g., practically any double-stranded cDNA clone generated using oligo dT as a primer).
  • polynucleotide ofthe present invention can be composed of any polyribonucleotide or polydeoxribonucleotide, which may be unmodified RNA or DNA or modified RNA or DNA.
  • polynucleotides can be composed of single- and double-stranded DNA, DNA that is a mixture of single- and double- stranded regions, single- and double-stranded RNA, and RNA that is mixture of single- and double-stranded regions, hybrid molecules comprising DNA and RNA that may be single-stranded or, more typically, double-stranded or a mixture of single- and double-stranded regions.
  • polynucleotide can be composed of triple-stranded regions comprising RNA or DNA or both RNA and DNA.
  • a polynucleotide may also contain one or more modified bases or DNA or RNA backbones modified for stability or for other reasons.
  • Modified bases include, for example, tritylated bases and unusual bases such as inosine.
  • a variety of modifications can be made to DNA and RNA; thus, "polynucleotide” embraces chemically, enzymatically, or metabolically modified forms.
  • the polypeptide ofthe present invention can be composed of amino acids joined to each other by peptide bonds or modified peptide bonds, i.e., peptide isosteres, and may contain amino acids other than the 20 gene-encoded amino acids.
  • the polypeptides may be modified by either natural processes, such as posttranslational processing, or by chemical modification techniques which are well known in the art. Such modifications are well described in basic texts and in more detailed monographs, as well as in a voluminous research literature. Modifications can occur anywhere in a polypeptide, including the peptide backbone, the amino acid side-chains and the amino or carboxyl termini.
  • polypeptides may be branched , for example, as a result of ubiquitination, and they may be cyclic, with or without branching. Cyclic, branched, and branched cyclic polypeptides may result from posttranslation natural processes or may be made by synthetic methods.
  • Modifications include acetylation, acylation, ADP-ribosylation, amidation, covalent attachment of flavin, covalent attachment ofa heme moiety, covalent attachment of a nucleotide or nucleotide derivative, covalent attachment of a lipid or lipid derivative, covalent attachment of phosphotidylinositol, cross-linking, cyclization, disulfide bond formation, demethylation, formation of covalent cross-links, formation of cysteine, formation of pyroglutamate, formylation, gamma-carboxylation, glycosylation, GPI anchor formation, hydroxylation, iodination, methylation, myristoylation, oxidation, pegylation, proteolytic processing, phosphorylation, prenylation, racemization, selenoylation, sulfation, transfer-RNA mediated addition of amino acids to proteins such as arginylation, and ubiquitination.
  • SEQ ID NO:X refers to a polynucleotide sequence while “SEQ ID NO:Y” refers to a polypeptide sequence, both sequences identified by an integer specified in Table 1.
  • a polypeptide having biological activity refers to polypeptides exhibiting activity similar, but not necessarily identical to, an activity of a polypeptide ofthe present invention, including mature forms, as measured in a particular biological assay, with or without dose dependency. In the case where dose dependency does exist, it need not be identical to that ofthe polypeptide, but rather substantially similar to the dose-dependence in a given activity as compared to the polypeptide ofthe present invention (i.e., the candidate polypeptide will exhibit greater activity or not more than about 25-fold less and, preferably, not more than about tenfold less activity, and most preferably, not more than about three-fold less activity relative to the polypeptide ofthe present invention.)
