                                        Comment: Sotatercept (MK-7962) is a soluble activin receptor 2A (ACVR2A; ActR2) ligand trap type inhibitor. Structurally it is a fusion protein of the extracellular domain of the ActR2 and a human IgG Fc domain.  In pulmonary blood vessels sotatercept sequesters ActR2 endogenous ligands (e.g. activins A and B, and growth differentiation factors 8 and 11, BMP6 and BMP7), and prevents their interaction with ActR2s to restore normal cell proliferation [3,7].
