Highly expressed in bone (PubMed:11746498, PubMed:17827158). Abundantly expressed in articular cartilage and chondrocytes and is increased in osteoarthritis (OA) (PubMed:11746498, PubMed:17827158). Colocalizes with ASPN in chondrocytes within OA lesions of articular cartilage (PubMed:17827158).

タンパク質の説明:
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

研究背景

機能:

Transforming growth factor beta-1 proprotein: Precursor of the Latency-associated peptide (LAP) and Transforming growth factor beta-1 (TGF-beta-1) chains, which constitute the regulatory and active subunit of TGF-beta-1, respectively.

Required to maintain the Transforming growth factor beta-1 (TGF-beta-1) chain in a latent state during storage in extracellular matrix. Associates non-covalently with TGF-beta-1 and regulates its activation via interaction with 'milieu molecules', such as LTBP1, LRRC32/GARP and LRRC33/NRROS, that control activation of TGF-beta-1. Interaction with LRRC33/NRROS regulates activation of TGF-beta-1 in macrophages and microglia (Probable). Interaction with LRRC32/GARP controls activation of TGF-beta-1 on the surface of activated regulatory T-cells (Tregs). Interaction with integrins (ITGAV:ITGB6 or ITGAV:ITGB8) results in distortion of the Latency-associated peptide chain and subsequent release of the active TGF-beta-1.

Transforming growth factor beta-1: Multifunctional protein that regulates the growth and differentiation of various cell types and is involved in various processes, such as normal development, immune function, microglia function and responses to neurodegeneration (By similarity). Activation into mature form follows different steps: following cleavage of the proprotein in the Golgi apparatus, Latency-associated peptide (LAP) and Transforming growth factor beta-1 (TGF-beta-1) chains remain non-covalently linked rendering TGF-beta-1 inactive during storage in extracellular matrix. At the same time, LAP chain interacts with 'milieu molecules', such as LTBP1, LRRC32/GARP and LRRC33/NRROS that control activation of TGF-beta-1 and maintain it in a latent state during storage in extracellular milieus. TGF-beta-1 is released from LAP by integrins (ITGAV:ITGB6 or ITGAV:ITGB8): integrin-binding to LAP stabilizes an alternative conformation of the LAP bowtie tail and results in distortion of the LAP chain and subsequent release of the active TGF-beta-1. Once activated following release of LAP, TGF-beta-1 acts by binding to TGF-beta receptors (TGFBR1 and TGFBR2), which transduce signal. While expressed by many cells types, TGF-beta-1 only has a very localized range of action within cell environment thanks to fine regulation of its activation by Latency-associated peptide chain (LAP) and 'milieu molecules' (By similarity). Plays an important role in bone remodeling: acts as a potent stimulator of osteoblastic bone formation, causing chemotaxis, proliferation and differentiation in committed osteoblasts (By similarity). Can promote either T-helper 17 cells (Th17) or regulatory T-cells (Treg) lineage differentiation in a concentration-dependent manner (By similarity). At high concentrations, leads to FOXP3-mediated suppression of RORC and down-regulation of IL-17 expression, favoring Treg cell development (By similarity). At low concentrations in concert with IL-6 and IL-21, leads to expression of the IL-17 and IL-23 receptors, favoring differentiation to Th17 cells (By similarity). Stimulates sustained production of collagen through the activation of CREB3L1 by regulated intramembrane proteolysis (RIP). Mediates SMAD2/3 activation by inducing its phosphorylation and subsequent translocation to the nucleus. Can induce epithelial-to-mesenchymal transition (EMT) and cell migration in various cell types.

PTMs:

Transforming growth factor beta-1 proprotein: The precursor proprotein is cleaved in the Golgi apparatus by FURIN to form Transforming growth factor beta-1 (TGF-beta-1) and Latency-associated peptide (LAP) chains, which remain non-covalently linked, rendering TGF-beta-1 inactive.

N-glycosylated. Deglycosylation leads to activation of Transforming growth factor beta-1 (TGF-beta-1); mechanisms triggering deglycosylation-driven activation of TGF-beta-1 are however unclear.

組織特異性:

Highly expressed in bone. Abundantly expressed in articular cartilage and chondrocytes and is increased in osteoarthritis (OA). Colocalizes with ASPN in chondrocytes within OA lesions of articular cartilage.

サブユニット構造:

Homodimer; disulfide-linked. 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 (By similarity). May interact with THSD4; this interaction may lead to sequestration by FBN1 microfibril assembly and attenuation of TGFB signaling (By similarity). Interacts with CD109, DPT and ASPN. Latency-associated peptide: Homodimer; disulfide-linked. Latency-associated peptide: Interacts with Transforming growth factor beta-1 (TGF-beta-1) chain; interaction is non-covalent and maintains (TGF-beta-1) in a latent state; each Latency-associated peptide (LAP) monomer interacts with TGF-beta-1 in the other monomer. Latency-associated peptide: Interacts with LTBP1; leading to regulate activation of TGF-beta-1. Latency-associated peptide: Interacts with LRRC32/GARP; leading to regulate activation of TGF-beta-1 on the surface of activated regulatory T-cells (Tregs). Interacts with LRRC33/NRROS; leading to regulate activation of TGF-beta-1 in macrophages and microglia (Probable). Latency-associated peptide: Interacts (via cell attachment site) with integrins ITGAV and ITGB6 (ITGAV:ITGB6), leading to release of the active TGF-beta-1. Latency-associated peptide: Interacts with NREP; the interaction results in a decrease in TGFB1 autoinduction (By similarity). Latency-associated peptide: Interacts with HSP90AB1; inhibits latent TGFB1 activation. Transforming growth factor beta-1: Homodimer; disulfide-linked. Transforming growth factor beta-1: Interacts with TGF-beta receptors (TGFBR1 and TGFBR2), leading to signal transduction.

タンパク質ファミリー:

The 'straitjacket' and 'arm' domains encircle the Transforming growth factor beta-1 (TGF-beta-1) monomers and are fastened together by strong bonding between Lys-56 and Tyr-103/Tyr-104.

The cell attachment site motif mediates binding to integrins (ITGAV:ITGB6 or ITGAV:ITGB8) (PubMed:28117447). The motif locates to a long loop in the arm domain called the bowtie tail (PubMed:28117447). Integrin-binding stabilizes an alternative conformation of the bowtie tail (PubMed:28117447). Activation by integrin requires force application by the actin cytoskeleton, which is resisted by the 'milieu molecules' (such as LTBP1, LRRC32/GARP and/or LRRC33/NRROS), resulting in distortion of the prodomain and release of the active TGF-beta-1 (PubMed:28117447).

Belongs to the TGF-beta family.
