TGF beta is a multifunctional peptide that controls proliferation, differentiation, and other functions in many cell types. TGFB acts synergistically with TGFA in inducing transformation. It also acts as a negative autocrine growth factor. Dysregulation of TGFB activation and signaling may result in apoptosis. Many cells synthesize TGFB and almost all of them have specific receptors for this peptide. It plays an important role in bone remodeling. It is a potent stimulator of osteoblastic bone formation, causing chemotaxis, proliferation, and differentiation in committed osteoblasts.
Recombinant protein corresponding to aa30-390 from human TGFb1 fused to His-tag at N-terminal and disulfide-linked homodimers of TGFb1 LAP and mature TGFb1 expressed in FreeStyle 293-F cells.
