Human chemokine beta-13

An isolated nucleic acid molecule comprising a polynucleotide having a nucleotide sequence at least 95% identical to a sequence selected from the group consisting of:

• (a) a nucleotide sequence encoding a polypeptide comprising the amino acid sequence of residues n-93 of SEQ ID NO:2, where n is an integer in the range of 1-35;
• (b) a nucleotide sequence encoding a polypeptide comprising the amino acid sequence of residues 1-m of SEQ ID NO:2, where m is an integer in the range of 77-93;
• (c) a nucleotide sequence encoding a polypeptide having the amino acid sequence consisting of residues n-m of SEQ ID NO:2, where n and m are integers as defined respectively in (a) and (b) above;
• and
• (d) a nucleotide sequence encoding a polypeptide consisting of a portion of the complete CKβ-13 amino acid sequence encoded by the cDNA clone contained in ATCC Deposit No. 97113 wherein said portion excludes from 1 to about 35 amino acids from the amino terminus of said complete amino acid sequence;
• (e) a nucleotide sequence encoding a polypeptide consisting of a portion of the complete CKβ-13 amino acid sequence encoded by the cDNA clone contained in ATCC Deposit No. 97113 wherein said portion excludes from 1 to about 17 amino acids from the carboxy terminus of said complete amino acid sequence;
• and
• (f) a nucleotide sequence encoding a polypeptide consisting of a portion of the complete CKβ-13 amino acid sequence encoded by the cDNA clone contained in ATCC Deposit No. 97113 wherein said portion include a combination of any of the amino terminal and carboxy terminal deletions in (d) and (e), above.

An isolated polypeptide comprising an epitope-bearing portion of the CKβ-13 protein, wherein said portion is selected from the group consisting of:

• a polypeptide comprising a mino acid residues from about Asn-30 to about Leu47 (SEQ ID NO:2);
• a polypeptide comprising amino acid residues from about Thr-56 to about Val-65 (SEQ ID NO:2);
• and a polypeptide comprising amino acid residues from about Phe-70 to about Trp-83 (SEQ ID NO:2).
