Inhibins appear to oppose the functions of activins. Activin B is a dimer of alpha and beta-B that plays a role in several essential biological processes including embryonic development, stem cell maintenance and differentiation, haematopoiesis, cell proliferation and wound healing. Signals through type I receptor ACVR1C, abundantly expressed in pancreatic beta cells, and type II receptors like ACVR2A or BMPR2. Upon ligand binding, these receptors phosphorylate intracellular signalling mediators SMAD2 and SMAD3, which form a complex with SMAD4, translocate to the nucleus, and regulate gene expression.
