Patent ID: 7393651

Claim:
An isolated polypeptide comprising: a) SEQ ID NO: 13; b) amino acids 1-291 of SEQ ID NO: 13; or c) the amino acid sequence encoded by: i) a nucleic acid encoding the amino acid sequence as set forth in SEQ ID NO:13; ii) a nucleic acid which hybridizes under highly stringent conditions to a nucleic acid that is the full complement of the nucleic acid encoding the amino acid sequence as set forth in SEQ ID NO:13, said highly stringent conditions include hybridization at 62° C. in buffer containing 50% formamide and a final wash at 67° C. in 0.5× SSC and 0.1% SDS and wherein said amino acid sequence increases transendothelial migration of leukocytes; or iii) a nucleic acid encoding a polypeptide comprising amino acids 1-291 of SEQ ID NO: 13.
