Description
Myostatin (from the MSTN gene) is a protein primarily made by skeletal muscles that acts as a brake, limiting muscle growth (negative regulation) to prevent muscles from getting too big. When myostatin is blocked or deficient, as seen in certain animals and rare human cases, it leads to significant muscle overgrowth (hypertrophy). Researchers are studying myostatin inhibitors as treatments for muscle-wasting diseases like muscular dystrophies, as blocking it could help patients build muscle mass.
Function
Regulates Muscle Mass:
Myostatin’s main job is to tell your muscles to stop growing once they reach a certain size.
Part of TGF-β Family:
It belongs to a group of proteins that control tissue growth and development.
