Abstract excerpt
Bone morphogenetic proteins (BMPs) are members of the TGF-beta family that regulate cell proliferation, apoptosis, and differentiation, and participate in the development of most tissues and organs in vertebrates. Smad proteins function downstream of TGF-beta receptor serine/threonine kinases and undergo serine phosphorylation in response to receptor activation. Smad1 is regulated in this fashion by BMP...
