Patent ID: 8323964

Claim:
An isolated polynucleotide encoding a mammalian promyostatin polypeptide fragment selected from the group consisting of a) a human promyostatin polypeptide consisting of an amino acid sequence as set forth in SEQ ID NO: 2 from 1 to about 262 or from 20 to about 262; b) a murine promyostatin polypeptide consisting of an amino acid sequence as set forth in SEQ ID NO: 4 from 1 to about 263 or from 20 to about 263; c) a rat promyostatin polypeptide consisting of an amino acid sequence as set forth in SEQ ID NO: 6 from 1 to about 263 or from 20 to about 263; d) a baboon promyostatin polypeptide consisting of an amino acid sequence as set forth in SEQ ID NO: 10 from 1 to about 262 or from 20 to about 262; e) a bovine promyostatin polypeptide consisting of an amino acid sequence as set forth in SEQ ID NO: 12 from 1 to about 262 or from 20 to about 262; f) a porcine promyostatin polypeptide consisting of an ammo acid sequence as set forth in SEQ ID NO: 14 from 1 to about 262 or from 20 to about 262; and g) an ovine promyostatin polypeptide consisting of an amino acid sequence as set forth in SEQ ID NO: 16 from 1 to about 262 or from 20 to about 262.
