Patent ID: 7883868

Claim:
An isolated nucleic acid molecule encoding polypeptide comprising the amino acid sequence selected from the group consisting of: (a) the amino acid sequence as set forth in SEQ ID NO:3, further comprising an amino-terminal methionine; (b) an amino acid sequence that is at least 95% identical to the amino acid sequence of SEQ ID NO:3; (c) a fragment of the amino acid sequence set forth in SEQ ID NO:3 comprising at least about 75 amino acid residues; (d) the amino acid sequence set forth in SEQ ID NO:3 having 1 to 25 conservative amino acid substitutions; (e) the amino acid sequence set forth in SEQ ID NO:3 having 1 to 25 amino acids inserted; and (f) the amino acid sequence set forth in SEQ ID NO:3 having 1 to 25 amino acids deleted wherein said polypeptide binds the alpha-2 subunit.
