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. Mediates CC induction of adipogenesis by GDF6. {ECO:0000250|UniProtKB:P27037, CC ECO:0000250|UniProtKB:P27038}.
