It is a tumor suppressor gene.{{cite web |url=http://ghr.nlm.nih.gov/gene=tgfbr2 |title=TGFBR2 - transforming growth factor, beta receptor II (70/80kDa) - Genetics Home Reference |access-date=2008-09-07 |archive-date=2011-08-10 |archive-url=https://web.archive.org/web/20110810091540/http://ghr.nlm.nih.gov/gene=TGFBR2 |url-status=dead }}

Function

This gene encodes a member of the serine/threonine protein kinase family and the TGFB receptor subfamily. The encoded protein is a transmembrane protein that has a protein kinase domain, forms a heterodimeric complex with another receptor protein, and binds TGF-beta. This receptor/ligand complex phosphorylates proteins, which then enter the nucleus and regulate the transcription of a subset of genes related to cell proliferation. Mutations in this gene have been associated with Marfan syndrome, Loeys-Deitz aortic aneurysm syndrome, Osler–Weber–Rendu syndrome, and the development of various types of tumors. At least 73 disease-causing mutations in this gene have been discovered.{{cite journal | vauthors = Šimčíková D, Heneberg P | title = Refinement of evolutionary medicine predictions based on clinical evidence for the manifestations of Mendelian diseases | journal = Scientific Reports | volume = 9 | issue = 1 | pages = 18577 | date = December 2019 | pmid = 31819097 | pmc = 6901466 | doi = 10.1038/s41598-019-54976-4| bibcode = 2019NatSR...918577S }} Alternatively spliced transcript variants encoding different isoforms have been characterized.{{cite web | title = Entrez Gene: TGFBR2 transforming growth factor, beta receptor II (70/80kDa)| url = https://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=7048}}

TGF beta receptor 2 consists of a C-terminal protein kinase domain and an N-terminal ectodomain. The ectodomain consists of a compact fold containing nine beta-strands and a single helix stabilised by a network of six intra strand disulphide bonds. The folding topology includes a central five-stranded antiparallel beta-sheet, eight-residues long at its centre, covered by a second layer consisting of two segments of two-stranded antiparallel beta-sheets (beta1-beta4, beta3-beta9).
