ACE-031 Mechanism of Action
Understanding how ACE-031 works at the molecular level reveals its documented research effects.
Mechanism of Action
ACE-031 acts as a ligand trap for members of the TGF-beta superfamily. By mimicking the extracellular domain of the ActRIIB receptor, it intercepts myostatin (GDF-8), activin A, activin B, and GDF-11 before they can bind cell-surface receptors and activate Smad2/3 signaling. Blocking this pathway removes the natural brake on muscle protein synthesis and satellite cell proliferation, resulting in rapid skeletal muscle hypertrophy. The Fc fusion domain extends circulating half-life through FcRn-mediated recycling and provides bivalent ligand binding.
