Patent ID: 7258999

Claim:
An isolated polypeptide encoded by an isolated nucleic acid fragment selected from the group consisting of: (a) an isolated nucleic acid fragment encoding SEQ ID NO: 2; (b) an isolated nucleic acid fragment encoding an amino acid sequence having at least 98% identity with SEQ ID NO: 2; and (c) an isolated nucleic acid fragment that hybridizes with the isolated nucleic acid fragment of (a) under hybridization conditions of 6×SSC (1M NaCl), 45 to 50% formamide, 1% SDS at 37° C., and a wash in 0.5× to 1×SSC at 55 to 60° C.; wherein said polypeptide is parathyroid hormone anabolic induced gene in bone (PAIGB) polypeptide and has osteoblast bone forming activity in bone tissues.
