Recombinant Human BMP-2 Protein

Description
BMP-2 is a member of the Bone Morphogenetic Protein (BMPs) family, which is important for the development of bone and cartilage. BMPs belong to the TGF-β superfamily of structurally related signaling proteins. BMP proteins are synthesized as large precursor molecules that are cleaved by proteolytic enzymes. The active form of BMPs can consist of a dimer of two identical proteins or a heterodimer of two related bone morphogenetic proteins. BMPs signal through type I and type II receptor tyrosine kinases and signal through SMAD proteins.
BMP-2 is a potent osteoinductive cytokine, capable of inducing bone and cartilage formation in association with an osteoconductive carrier such as collagen and synthetic hydroxyapatite. In addition to its osteogenic activity, BMP-2 appears to play an important role in cardiac morphogenesis, and is expressed in a variety of other tissues, including lung, liver, spleen, prostate, ovary, and small intestine.
