Mouse Activin A Receptor Type 2B (ACVR2B) Protein

Background

ACVR2B is another type II receptor involved in activin and myostatin signaling pathways. It phosphorylates type I receptors (e.g., ACVR1B) to activate SMAD-dependent signaling cascades. ACVR2B regulates processes like muscle growth, reproductive function, and embryonic development. Inhibition of ACVR2B has been explored as a therapeutic approach for muscle-wasting disorders, such as cachexia and muscular dystrophy. Mutations in ACVR2B can impair ligand-receptor interactions, leading to developmental defects.
