Myostatin (MSTN) Human Active Protein

The protein encoded by this gene is a member of the bone morphogenetic protein (BMP) family and the TGF-beta superfamily. This group of proteins is characterized by a polybasic proteolytic processing site which is cleaved to produce a mature protein containing seven conserved cysteine residues. The members of this family are regulators of cell growth and differentiation in both embryonic and adult tissues. This gene is thought to encode a secreted protein which negatively regulates skeletal muscle growth. [provided by RefSeq, Jul 2008]

MSTN: Acts specifically as a negative regulator of skeletal muscle growth. Defects in MSTN are the cause of muscle hypertrophy (MSLHP). MSLHP is a condition characterized by increased muscle bulk and strength. Affected individuals are exceptionally strong. Belongs to the TGF-beta family.
