Bone Morphogenetic Proteins (BMPs) are TGF-β-like secreted signaling molecules that play important roles in tissue homeostasis and diseases, such as cancer. Although different, BMP2 (UniProtKB P12643) and BMP4 (UniProtKB P12644) originate from the same gene and show >80% sequence homology. Both BMP2 and BMP4 preferentially bind to the type I BMP receptors, BMPR1A (Alk3) and BMPR1B (Alk6), but can also signal through ActRI (Alk2).
Source:
