Bone morphogenetic protein 3

Bone morphogenetic protein 3 (BMP3) is a polypeptide member of the Transforming growth factor beta superfamily of proteins. It, like other bone morphogenetic proteins (BMP's) is known for its ability to induce bone and cartilage development. It is a disulphide-linked homodimer. It negatively regulates bone density. BMP3 is an antagonist to other BMP's in the differentiation of osteogenic progenitors.

It is highly expressed in fractured tissues.
