Transforming Growth Factor-Beta 1 (113 amino acids), human recombinant (rHuTGF-b1)

Multifunctional protein that controls proliferation, differentiation and other functions in many cell types. Many cells synthesize TGFB1 and have specific receptors for it. It positively and negatively regulates many other growth factors. It plays an important role in bone remodeling as it is a potent stimulator of osteoblastic bone formation, causing chemotaxis, proliferation and differentiation in committed osteoblasts. (www.uniprot.org) Human recombinant TGF-b 1 produced in E.coli is a single, non-glycosylated, polypeptide chain containing 113 amino acids (fragment 279-390) and having a total molecular mass of 12.9 kDa. Transforming growth factor betas (TGFBetas) mediate many cell-cell interactions that occur during embryonic development. Three TGFBetas have been identified in mammals. TGFBeta1, TGFBeta2 and TGFBeta3 are each synthesized as precursor proteins that are very similar in that each is cleaved to yield a 112 amino acid polypeptide that remains associated with the latent portion of the molecule.
