Precursor of the Latency-associated peptide (LAP) and Transforming growth factor beta-2 (TGF-beta-2) chains, which constitute the regulatory and active subunit of TGF-beta-2, respectively. Required to maintain the Transforming growth factor beta-2 (TGF-beta-2) chain in a latent state during storage in extracellular matrix (By similarity). Associates non-covalently with TGF-beta-2 and regulates its activation via interaction with 'milieu molecules', such as LTBP1 and LRRC32/GARP, that control activation of TGF-beta-2 (By similarity). Multifunctional protein that regulates various processes such as angiogenesis and heart development (PubMed:22772371, PubMed:22772368). 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-2 (TGF-beta-2) chains remain non-covalently linked rendering TGF-beta-2 inactive during storage in extracellular matrix (By similarity). At the same time, LAP chain interacts with 'milieu molecules', such as LTBP1 and LRRC32/GARP, that control activation of TGF-beta-2 and maintain it in a latent state during storage in extracellular milieus (By similarity). Once activated following release of LAP, TGF-beta-2 acts by binding to TGF-beta receptors (TGFBR1 and TGFBR2), which transduce signal (By similarity). Interacts with the serine proteases, HTRA1 and HTRA3 (By similarity). Interacts with ASPN (PubMed:17827158). Interacts with MFAP5 (By similarity). Interacts with Transforming growth factor beta-2 (TGF-beta-2) chain; interaction is non-covalent and maintains (TGF-beta-2) in a latent state (By similarity). Interacts with LRRC32/GARP; leading to regulate activation of TGF-beta-2 (PubMed:19651619). Interacts with NREP; the interaction results in a decrease in TGFB2 autoinduction (By similarity). Homodimer; disulfide-linked (PubMed:1631557, PubMed:1641027). Interacts with TGF-beta receptors (TGFBR1 and TGFBR2), leading to signal transduction (By similarity). The precursor proprotein is cleaved in the Golgi apparatus to form Transforming growth factor beta-2 (TGF-beta-2) and Latency-associated peptide (LAP) chains, which remain non-covalently linked, rendering TGF-beta-2 inactive. A chromosomal aberration involving TGFB2 is found in a family with Peters anomaly. Translocation t(1;7)(q41;p21) with HDAC9. The disease is caused by variants affecting the gene represented in this entry. Defects in TGFB2 may be a cause of non-syndromic aortic disease (NSAD). NSAD is a frequently asymptomatic but potentially lethal disease characterized by thoracic aortic aneurysms and dissections without additional syndromic features. Belongs to the TGF-beta family. In contrast to other members of the family, does not contain a R-G-D cell attachment site motif that mediates binding to integrins and promotes release of Latency-associated peptide (LAP) chain from TGF-beta-2.
