Activin Receptor Type IIB Decoy · Myostatin Pathway Inhibitor
Soluble decoy receptor targeting activin receptor type IIB (ActRIIB). Studied in muscle mass and bone density research models.
ACE-031 is a fusion protein combining the extracellular domain of activin receptor type IIB (ActRIIB) with an IgG1 Fc region. It acts as a decoy receptor, sequestering myostatin, activin, and GDF-11, thereby blocking their inhibitory effects on muscle growth. Research interest spans muscle-wasting diseases and athletic performance models.
Store at 2–8°C (refrigerated, not frozen). Sensitive protein — avoid freeze-thaw cycles.
