Function

[BMP7_HUMAN] Induces cartilage and bone formation. May be the osteoinductive factor responsible for the phenomenon of epithelial osteogenesis. Plays a role in calcium regulation and bone homeostasis. [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

Activins and bone morphogenetic proteins (BMPs) elicit diverse biological responses by signaling through two pairs of structurally related type I and type II receptors. Here we report the crystal structure of BMP7 in complex with the extracellular domain (ECD) of the activin type II receptor. Our structure produces a compelling four-receptor model, revealing that the types I and II receptor ECDs make no direct contacts. Nevertheless, we find that truncated receptors lacking their cytoplasmic domain retain the ability to cooperatively assemble in the cell membrane. Also, the affinity of BMP7 for its low-affinity type I receptor ECD increases 5-fold in the presence of its type II receptor ECD. Taken together, our results provide a view of the ligand-mediated cooperative assembly of BMP and activin receptors that does not rely on receptor-receptor contacts.

The BMP7/ActRII extracellular domain complex provides new insights into the cooperative nature of receptor assembly.,Greenwald J, Groppe J, Gray P, Wiater E, Kwiatkowski W, Vale W, Choe S Mol Cell. 2003 Mar;11(3):605-17. PMID:12667445^[1]
