products description :
TGF-beta is the prototype of a protein family known as the TGF-beta superfamily. This family includes Inhibins, Activin A, MIS (M llerian inhibiting substance), BMP (bone morphogenetic proteins), dpp (decapentaplegic) and Vg-1. Type 1 receptors and type 2 receptors have a molecular mass of 53 and 75 kDa, respectively. Signaling through the receptor requires heterodimeric complexes between both types of receptors. The type 2 receptor has been shown to bind the ligand, but it is incapable of mediating TGF- beta responses in the absence of the type 1 receptor. The type 1 receptor is expressed predominantly in hematopoietic progenitor cells. The type 2 receptor encodes a protein with an intracellular domain that functions as a serine/threonine kinase. TGF-beta is the most potent known growth inhibitor for normal and transformed epithelial cells, endothelial cells, fibroblasts, neuronal cells, lymphoid cells and other hematopoietic cell types. TGF-beta inhibits the proliferation of T- lymphocytes by down- regulating predominantly IL- 2 mediated proliferative signals. It also inhibits the growth of natural killer cells in vivo and deactivates macrophages. TGF-beta blocks the antitumor activity mediated in vivo by IL-2 and transferred lymphokine- activated or tumor infiltrating lymphocytes.

ncbi summary :
This gene encodes a member of the transforming growth factor beta (TGFB) family of cytokines, which are multifunctional peptides that regulate proliferation, differentiation, adhesion, migration, and other functions in many cell types. Many cells have TGFB receptors, and the protein positively and negatively regulates many other growth factors. The secreted protein is cleaved into a latency-associated peptide (LAP) and a mature TGFB1 peptide, and is found in either a latent form composed of a TGFB1 homodimer, a LAP homodimer, and a latent TGFB1-binding protein, or in an active form composed of a TGFB1 homodimer. The mature peptide may also form heterodimers with other TGFB family members. This gene is frequently upregulated in tumor cells, and mutations in this gene result in Camurati-Engelmann disease.[provided by RefSeq, Oct 2009]
uniprot summary :
TGFB1: 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. Homodimer; disulfide-linked, or heterodimer with TGFB2. Secreted and stored as a biologically inactive form in the extracellular matrix in a 290 kDa complex (large latent TGF-beta1 complex) containing the TGFB1 homodimer, the latency-associated peptide (LAP), and the latent TGFB1 binding protein-1 (LTBP1). The complex without LTBP1 is known as the small latent TGF-beta1 complex . Dissociation of the TGFB1 from LAP is required for growth factor activation and biological activity. Release of the large latent TGF-beta1 complex from the extracellular matrix is carried out by the matrix metalloproteinase MMP3. May interact with THSD4; this interaction may lead to sequestration by FBN1 microfibril assembly and attenuation of TGFB signaling. Interacts with the serine proteases, HTRA1 and HTRA3: the interaction with either inhibits TGFB1-mediated signaling. The HTRA protease activity is required for this inhibition. Interacts with CD109, DPT and ASPN. Activated in vitro at pH below 3.5 and over 12.5. Highly expressed in bone. Abundantly expressed in articular cartilage and chondrocytes and is increased in osteoarthritis (OA). Co-localizes with ASPN in chondrocytes within OA lesions of articular cartilage. Belongs to the TGF-beta family. Protein type: Secreted, signal peptide; Motility/polarity/chemotaxis; Secreted. Chromosomal Location of Human Ortholog: 19q13.1.
