Patent ID: 7198913

Claim:
An isolated nucleic acid comprising (a) a DNA molecule encoding a polypeptide having at least 95% sequence identity to the sequence of amino acid residues 1 to 299 of SEQ ID NO:3; (b) a DNA molecule encoding the same mature polypeptide encoded by the cDNA in ATCC Deposit No. 203906 (DNA98853); (c) a DNA molecule encoding a polypeptide which comprises amino acid residues 1 to X of FIG. 2 (SEQ ID NO:3), wherein X is any one of amino acid residues 131–141 of FIG. 2 (SEQ ID NO:3); or (d) the complement of the DNA molecule of (a), (b), or (c), wherein the polypeptide encoded by the DNA molecule of (a) or (c) is capable of activating NF-κB in a mammalian cell or binding to a native sequence EDA-A2 ligand.
