A portion of amino acids 1-30 from the human protein was used as the immunogen for this BMPR1A antibody.
On ligand binding, BMPR1A 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 BMP-2 and BMP-4. Positively regulates chondrocyte differentiation through GDF5 interaction (By similarity). [UniProt]
