+== Function ==
+[https://www.uniprot.org/uniprot/AVR2A_MOUSE AVR2A_MOUSE] On ligand binding, forms a receptor complex consisting of two type II and two type I transmembrane serine/threonine kinases. Type II receptors phosphorylate and activate type I receptors which autophosphorylate, then bind and activate SMAD transcriptional regulators. Receptor for activin A, activin B and inhibin A.

+== Publication Abstract from PubMed ==
+The transforming growth factor beta (TGFbeta) superfamily of cytokines elicit diverse biological responses by interacting with two distinct, but structurally related transmembrane receptor serine kinases (type I and type II). The binding of these dimeric ligands to the type II receptor is the first event in transmembrane signaling for this family. Here we report the 1.5 A resolution crystal structure of the extracellular ligand-binding domain of the type II activin receptor (ActRII-ECD), which reveals a fold similar to that of a class of toxins known as three-finger toxins. This fold is primarily dictated by disulfide bonds formed by eight conserved cysteines, with a characteristic spacing, and thus is likely to be shared by most of the type I and II receptors for the TGFbeta family. Sequence comparison with an evolutionarily distant activin binding-protein identifies several conserved residues, including two hydrophobic clusters that may form binding surfaces for activin and the type I receptor.
