CC -!- FUNCTION: Transforming growth factor beta-1 proprotein: Precursor of
CC the Latency-associated peptide (LAP) and Transforming growth factor
CC beta-1 (TGF-beta-1) chains, which constitute the regulatory and active
CC subunit of TGF-beta-1, respectively. {ECO:0000250|UniProtKB:P01137}.
CC -!- FUNCTION: [Latency-associated peptide]: Required to maintain the
CC Transforming growth factor beta-1 (TGF-beta-1) chain in a latent state
CC during storage in extracellular matrix. Associates non-covalently with
CC TGF-beta-1 and regulates its activation via interaction with 'milieu
CC molecules', such as LTBP1, LRRC32/GARP and LRRC33/NRROS, that control
CC activation of TGF-beta-1. Interaction with LRRC33/NRROS regulates
CC activation of TGF-beta-1 in macrophages and microglia. Interaction with
CC LRRC32/GARP controls activation of TGF-beta-1 on the surface of
CC activated regulatory T-cells (Tregs). Interaction with integrins
CC (ITGAV:ITGB6 or ITGAV:ITGB8) results in distortion of the Latency-
CC associated peptide chain and subsequent release of the active TGF-beta-
CC 1. {ECO:0000250|UniProtKB:P01137}.
CC -!- FUNCTION: [Transforming growth factor beta-1]: Multifunctional protein
CC that regulates the growth and differentiation of various cell types and
CC is involved in various processes, such as normal development, immune
CC function, microglia function and responses to neurodegeneration (By
CC similarity). Activation into mature form follows different steps:
CC following cleavage of the proprotein in the Golgi apparatus, Latency-
CC associated peptide (LAP) and Transforming growth factor beta-1 (TGF-
CC beta-1) chains remain non-covalently linked rendering TGF-beta-1
CC inactive during storage in extracellular matrix. At the same time, LAP
CC chain interacts with 'milieu molecules', such as LTBP1, LRRC32/GARP and
CC LRRC33/NRROS that control activation of TGF-beta-1 and maintain it in a
CC latent state during storage in extracellular milieus. TGF-beta-1 is
CC released from LAP by integrins (ITGAV:ITGB6 or ITGAV:ITGB8): integrin-
CC binding to LAP stabilizes an alternative conformation of the LAP bowtie
CC tail and results in distortion of the LAP chain and subsequent release
CC of the active TGF-beta-1. Once activated following release of LAP, TGF-
CC beta-1 acts by binding to TGF-beta receptors (TGFBR1 and TGFBR2), which
CC transduce signal (By similarity). While expressed by many cells types,
CC TGF-beta-1 only has a very localized range of action within cell
CC environment thanks to fine regulation of its activation by Latency-
CC associated peptide chain (LAP) and 'milieu molecules'. Plays an
CC important role in bone remodeling: acts as a potent stimulator of
CC osteoblastic bone formation, causing chemotaxis, proliferation and
CC differentiation in committed osteoblasts. Can promote either T-helper
CC 17 cells (Th17) or regulatory T-cells (Treg) lineage differentiation in
CC a concentration-dependent manner. At high concentrations, leads to
CC FOXP3-mediated suppression of RORC and down-regulation of IL-17
CC expression, favoring Treg cell development. At low concentrations in
CC concert with IL-6 and IL-21, leads to expression of the IL-17 and IL-23
CC receptors, favoring differentiation to Th17 cells (By similarity).
CC Stimulates sustained production of collagen through the activation of
CC CREB3L1 by regulated intramembrane proteolysis (RIP). Mediates SMAD2/3
CC activation by inducing its phosphorylation and subsequent translocation
CC to the nucleus. Can induce epithelial-to-mesenchymal transition (EMT)
CC and cell migration in various cell types (By similarity).
CC {ECO:0000250|UniProtKB:P01137, ECO:0000250|UniProtKB:P04202}.
CC -!- SUBUNIT: Homodimer; disulfide-linked. Interacts with the serine
CC proteases, HTRA1 and HTRA3: the interaction with either inhibits TGFB1-
CC mediated signaling and the HTRA protease activity is required for this
CC inhibition. May interact with THSD4; this interaction may lead to
CC sequestration by FBN1 microfibril assembly and attenuation of TGFB
CC signaling. Interacts with CD109, DPT and ASPN. Interacts with EFEMP2.
CC Interacts with TSKU; the interaction contributes to regulation of the
CC hair cycle. {ECO:0000250|UniProtKB:P01137,
CC ECO:0000250|UniProtKB:P04202}.
CC -!- SUBUNIT: [Latency-associated peptide]: Homodimer; disulfide-linked.
CC Interacts with transforming growth factor beta-1 (TGF-beta-1) chain;
CC interaction is non-covalent and maintains TGF-beta-1 in a latent state;
CC each latency-associated peptide (LAP) monomer interacts with TGF-beta-1
CC in the other monomer. Interacts with LTBP1; leading to regulation of
CC TGF-beta-1 activation. Interacts with LRRC32/GARP; leading to
CC regulation of TGF-beta-1 activation on the surface of activated
CC regulatory T-cells (Tregs). Interacts with LRRC33/NRROS; leading to
CC regulation of TGF-beta-1 activation in macrophages and microglia.
CC Interacts (via cell attachment site) with integrins ITGAV and ITGB6
CC (ITGAV:ITGB6), leading to release of the active TGF-beta-1. Interacts
CC with NREP; the interaction results in a decrease in TGFB1
CC autoinduction. Interacts with HSP90AB1; inhibits latent TGFB1
CC activation. {ECO:0000250|UniProtKB:P01137,
CC ECO:0000250|UniProtKB:P04202}.
CC -!- SUBUNIT: [Transforming growth factor beta-1]: Homodimer; disulfide-
CC linked. Interacts with TGF-beta receptors (TGFBR1 and TGFBR2), leading
CC to signal transduction. {ECO:0000250|UniProtKB:P01137}.
CC -!- SUBCELLULAR LOCATION: [Latency-associated peptide]: Secreted,
CC extracellular space, extracellular matrix
CC {ECO:0000250|UniProtKB:P01137}.
CC -!- SUBCELLULAR LOCATION: [Transforming growth factor beta-1]: Secreted
CC {ECO:0000250|UniProtKB:P01137}.
CC -!- DOMAIN: [Latency-associated peptide]: The 'straitjacket' and 'arm'
CC domains encircle the Transforming growth factor beta-1 (TGF-beta-1)
CC monomers and are fastened together by strong bonding between Lys-56 and
CC Tyr-103/Tyr-104. {ECO:0000250|UniProtKB:P07200}.
CC -!- DOMAIN: [Latency-associated peptide]: The cell attachment site motif
CC mediates binding to integrins (ITGAV:ITGB6 or ITGAV:ITGB8). The motif
CC locates to a long loop in the arm domain called the bowtie tail.
CC Integrin-binding stabilizes an alternative conformation of the bowtie
CC tail. Activation by integrin requires force application by the actin
CC cytoskeleton, which is resisted by the 'milieu molecules' (such as
CC LTBP1, LRRC32/GARP and/or LRRC33/NRROS), resulting in distortion of the
CC prodomain and release of the active TGF-beta-1.
CC {ECO:0000250|UniProtKB:P01137}.
CC -!- PTM: Transforming growth factor beta-1 proprotein: The precursor
CC proprotein is cleaved in the Golgi apparatus by FURIN to form
CC Transforming growth factor beta-1 (TGF-beta-1) and Latency-associated
CC peptide (LAP) chains, which remain non-covalently linked, rendering
CC TGF-beta-1 inactive. {ECO:0000250|UniProtKB:P01137}.
CC -!- PTM: [Latency-associated peptide]: N-glycosylated. Deglycosylation
CC leads to activation of Transforming growth factor beta-1 (TGF-beta-1);
CC mechanisms triggering deglycosylation-driven activation of TGF-beta-1
CC are however unclear. {ECO:0000250|UniProtKB:P01137}.
CC -!- SIMILARITY: Belongs to the TGF-beta family. {ECO:0000305}.
