CD292; bone morphogenetic protein receptor type-1A; serine/threonine protein kinase receptor R5; SKR5; activin receptor-like kinase 3; ALK-3 (BMPR1A, ACVRLK3, ALK3)

Function: - on ligand binding, forms a receptor complex consisting of 2 type II & 2 type I transmembrane serine/threonine kinases - type II receptors phosphorylate & activate type I receptors which autophosphorylate, then bind & activate SMAD transcriptional regulators - receptor for BMP-2 & BMP-4 Cofactor: Mg+2 or Mn+2 (putative) Structure: - belongs to the protein kinase superfamily, TKL Ser/Thr protein kinase family, TGFB receptor subfamily - contains 1 GS domain - contains 1 protein kinase domain Compartment: membrane Expression: highly expressed in skeletal muscle Pathology: - defects in BMPR1A are a cause of a) juvenile polyposis syndrome b) Cowden disease c) hereditary mixed polyposis syndrome 2 - microdeletion of chromosome 10q23 involving BMPR1A & PTEN is a cause of chromosome 10q23 deletion syndrome
