Myostatin
Myostatin — A member of the TGF-beta superfamily that functions as a negative regulator of skeletal muscle growth, making it a target in muscle biology research.
What Is Myostatin?
Myostatin (GDF-8) is a TGF-beta superfamily member that negatively regulates skeletal muscle growth. Myostatin inhibition (by antibodies, propeptide, or decoy receptors) causes dramatic muscle hypertrophy. Peptide-based myostatin inhibitors and myostatin-binding peptides are actively studied for sarcopenia, muscular dystrophy, and cachexia.
Peptide Approaches
- Myostatin propeptide: The endogenous inhibitor. Recombinant propeptide blocks myostatin signaling
- Follistatin peptides: Follistatin-derived sequences that bind and neutralize myostatin
- ACE-031: ActRIIB-Fc decoy receptor (peptide/protein fusion) that sequesters myostatin
