Platelet Derived Growth Factor BB (PDGFBB) (Active) protein
Description
PDGFs are disulfide-linked dimers consisting of two 12.0-13.5 kDa polypeptide chains, designated PDGF-A and PDGF-B chains. The three naturally occurring PDGFs, PDGF-AA, PDGF-BB and PDGF-AB, are potent mitogens for a variety of cell types including smooth muscle cells, connective tissue cells, bone and cartilage cells, and some blood cells. The PDGFs are stored in platelet a-granules and are released upon platelet activation. The PDGFs are involved in a number of biological processes, including hyperplasia, chemotaxis, embryonic neuron development, and respiratory tubule epithelial cell development. Two distinct signaling receptors used by PDGFs have been identified and named PDGFR-a and PDGFR-beta. PDGFR-a is high-affinity receptor for each of the three PDGF forms. Alternative Names: Osteosarcoma-derived Growth Factor protein, Platelet-Derived Growth Factor-BB protein, GDGF protein, Glioma-derived growth factor protein, ODGF protein
