== 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. Alternatively spliced transcript variants encoding different isoforms have been characterized.<ref>{{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| accessdate = }}</ref>

TGF beta receptor 2 consists of a [[C-terminal]] [[protein kinase domain]] and an [[N-terminal]] ectodomain. The ectodomain consists of a compact [[protein folding|fold]] containing nine beta-strands and a single [[alpha helix|helix]] stabilised by a network of six intra strand [[disulphide bonds]]. The [[protein folding|folding]] topology includes a central five-stranded [[Antiparallel (biochemistry)|antiparallel]] beta-sheet, eight-residues long at its centre, covered by a second layer consisting of two segments of two-stranded antiparallel [[beta-sheet]]s (beta1-beta4, beta3-beta9).<ref name="pmid11850637"/>
