Bone Morphogenetic Protein Receptor IA (BMPR-IA), also known as ALK-3, BRK-1, and CD292, is a glycosylated 60 - 65 kDa type I receptor in the TGF‑ beta serine/threonine kinase receptor family (1 ‑ 3). Binding of TGF-beta superfamily ligands induces formation of a heterotetrameric complex that contains two chains each of a type I and a type II receptor in multiple combinations. The type II receptors phosphorylate the type I receptors which then phosphorylate and activate Smad signal transduction proteins (1, 2). Mature human BMPR-IA consisits of a 129 amino acid (aa) extracellular domain (ECD), a 24 aa transmembrane segment, and a 356 aa cytoplasmic region that contains the tyrosine kinase domain (4). Within the ECD, human BMPR-IA shares 98% and 97% aa sequence identity with mouse and rat BMPR-IA, respectively. BMPR-IA is involved in the development and function of a wide range of tissues. During early embryogenesis it is required for migration of the anterior visceral endoderm (AVE) and proper development of the anterior-posterior axis (5). Tissue-specific conditional knockout experiments have demonstrated the importance of BMPR-IA in the development and morphogenesis of the heart, lung, palate, teeth, and mandible (6 - 8). In the adult, BMPR-IA plays a role in glucose-stimulated insulin secretion by pancreatic beta cells, osteoclast activity and bone remodeling, reactive astrocyte-mediated scar formation following spinal cord injury, and ovulation and fertility (9 - 12).
