CC -!- FUNCTION: On ligand binding, forms a receptor complex consisting of two
CC type II and two type I transmembrane serine/threonine kinases. Type II
CC receptors phosphorylate and activate type I receptors which
CC autophosphorylate, then bind and activate SMAD transcriptional
CC regulators. Receptor for activin A, activin B and inhibin A. May
CC modulate neuropeptide expression in dorsal root ganglia (DRG) neurons
CC and ovarian follicle development. {ECO:0000269|PubMed:11291100,
