ACVR2B is a transmembrane kinase that forms the activin receptor complex and is essential for transducing activin signals. It regulates diverse processes including neuronal differentiation, hair follicle development, FSH production, wound healing, matrix production, immunosuppression, and carcinogenesis. ACVR2B Protein, Human/Cynomolgus (P. pastoris, N-His) is the recombinant human-derived ACVR2B protein, expressed by P. pastoris , with N-6*His labeled tag.
