TGFB2

This gene encodes a secreted ligand of the TGF-beta (transforming growth factor-beta) superfamily of proteins. Ligands of this family bind various TGF-beta receptors leading to recruitment and activation of SMAD family transcription factors that regulate gene expression. The encoded preproprotein is proteolytically processed to generate a latency-associated peptide (LAP) and a mature peptide, and is found in either a latent form composed of a mature peptide homodimer, a LAP homodimer, and a latent TGF-beta binding protein, or in an active form consisting solely of the mature peptide homodimer. The mature peptide may also form heterodimers with other TGF-beta family members. Disruption of the TGF-beta/SMAD pathway has been implicated in a variety of human cancers. A chromosomal translocation that includes this gene is associated with Peters' anomaly, a congenital defect of the anterior chamber of the eye. Mutations in this gene may be associated with Loeys-Dietz syndrome. This gene encodes multiple isoforms that may undergo similar proteolytic processing. [provided by RefSeq, Aug 2016]

Interaction

Interacts with the serine proteases, HTRA1 and HTRA3 (By similarity). Interacts with ASPN (PubMed:17827158). Interacts with MFAP5 (By similarity). Latency-associated peptide: 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). Latency-associated peptide: Interacts with LRRC32/GARP; leading to regulate activation of TGF-beta-2 (PubMed:19651619). Latency-associated peptide: Interacts with NREP; the interaction results in a decrease in TGFB2 autoinduction (By similarity). Transforming growth factor beta-2: Homodimer; disulfide-linked (PubMed:1631557, PubMed:1641027). Transforming growth factor beta-2: Interacts with TGF-beta receptors (TGFBR1 and TGFBR2), leading to signal transduction (By similarity).
