BMP-3 Protein, Human

BMP-3 Protein, a TGF-beta superfamily member, crucially influences early skeletal formation and acts as a bone density negative regulator. It counteracts osteogenic BMPs, hindering osteoprogenitor differentiation. BMP-3 initiates signaling via ACVR2B, activating SMAD2-dependent and SMAD-independent pathways, including TAK1 and JNK. Structurally, it forms homodimers with disulfide bonds, interacting with ACVR2B to regulate functions. BMP-3 Protein, Human is the recombinant human-derived BMP-3 protein, expressed by E. coli , with tag free.

BMP-3 Protein, a member of the TGF-beta superfamily, plays a crucial role in developmental processes, particularly in inducing and patterning early skeletal formation, while concurrently acting as a negative regulator of bone density. Notably, it counteracts the osteogenic BMPs' ability to induce osteoprogenitor differentiation and ossification. The initiation of signaling cascades involves BMP-3 associating with the type II receptor ACVR2B, activating both SMAD2-dependent and SMAD-independent pathways, including TAK1 and JNK pathways. Structurally, BMP-3 exists as a homodimer linked by disulfide bonds and interacts with the type II receptor ACVR2B to exert its regulatory functions.

Measured by its ability to inhibit BMP-2-induced alkaline phosphatase production by MC3T3-E1 mouse preosteoblast cells. 30 µg/mL of hBMP-3 will antagonize hBMP-2 (0.25 µg/mL) induction of alkaline phosphatase in MC3T3E1 cells by 52.83%.
