TGFβ1 / TGFB1 Protein Description

Transforming growth factor beta 1 (TGFβ1) is a member of the large transforming growth factor beta superfamily of cytokines, and serves as a multifunctional molecule performing actions in many cellular functions, including the control of cell growth, cell proliferation, cell differentiation and apoptosis. TGFβ1 was first synthesized as a 390 amino acid precusor. The secreted proprotein contains 360 aa, and is cleaved into mature TGFβ1(112 aa) and latency-associated peptide (LAP)( 248 aa), which remains non-covalently linked to mature TGFβ1 rendering it inactive. TGFβ1 is synthesized by many cells, and regulates many other growth factors both in positive and negative manner. It has been shown that TGFβ1 plays an important role in controlling the immune system and shows different activities on different types of cell, or cells at different developmental stages. Highly expressed in bone and as a potent stimulator of osteoblastic bone formation, TGFβ1 is able to cause chemotaxis, proliferation and differentiation in committed osteoblasts. Further, TGFβ1 is also identified as a disease marker and a therapeutical target for cardiovascular disease. TGFβ activation from latency is controlled by multiple pathways including actions of some proteases, such as MMP9 and plasmin.
