Patent ID: 7160694

Claim:
An isolated nucleic acid molecule selected from the group consisting of: a) a nucleic acid molecule comprising a nucleotide sequence which is at least 95% identical to the nucleotide sequence of any of SEQ ID NO:51, SEQ ID NO:52, or the nucleotide sequence of the clone deposited as ATCC Accession number PTA-424, wherein the nucleotide sequence encodes a polypeptide capable of mediating T-cell activation; b) a nucleic acid molecule which encodes a polypeptide which is at least 95% identical to the amino acid sequence of SEQ ID NO:53, wherein the polypeptide is capable of mediating T-cell activation; c) a nucleic acid molecule comprising the nucleotide sequence of any of SEQ ID NO:51, SEQ ID NO:52, or the nucleotide sequence of the clone deposited as ATCC Accession PTA-424, or a full complement thereof; and d) a nucleic acid molecule which encodes a polypeptide comprising the amino acid sequence of SEQ ID NO: 53, or the amino acid sequence encoded by the nucleotide sequence of the clone deposited as ATCC Accession number PTA-424.
