Activin proteins that belong to the transforming growth factor-beta (TGF-β) superfamily; exert their biological actions by binding to heteromeric receptor complexes of type I and type II serine/threonine kinase receptors. On ligand binding; type I and II receptors form a stable complex; resulting in phosphorylation of type I receptors by type II receptors with constitutive kinase activity; and subsequently initiates the activation of downstream molecules including the endogenous Smads. ActRIIB; also known as ActRIIB; is a type II receptor containing an extracellular domain (ECD); a transmembrane segment; and a cytoplasmic region that includes the kinase domain. ActRIIB is a receptor for activin A; activin B and inhibin A. Multiple ActRIIB isoforms can also be generated; which bind activin isoforms with different affinities.
