## TL;DR

TGFBR2 (TGF-beta receptor type-2) is a protein kinase, an enzyme that switches other proteins on by adding phosphate groups. The public catalogues list it as an oncogene driver and a tumour suppressor, and it is called a cancer driver by mutation analysis of patient cohorts. Tied to Colorectal cancer, Oesophageal cancer, Pancreatic ductal adenocarcinoma and 5 more.

## Summary

Transmembrane serine/threonine kinase forming with the TGF-beta type I serine/threonine kinase receptor, TGFBR1, the non-promiscuous receptor for the TGF-beta cytokines TGFB1, TGFB2 and TGFB3. Transduces the TGFB1, TGFB2 and TGFB3 signal from the cell surface to the cytoplasm and thus regulates a plethora of physiological and pathological processes including cell cycle arrest in epithelial and haematopoietic cells, control of mesenchymal cell proliferation and differentiation, wound healing, extracellular matrix production, immunosuppression and carcinogenesis. The formation of the receptor complex composed of 2 TGFBR1 and 2 TGFBR2 molecules symmetrically bound to the cytokine dimer results in the phosphorylation and activation of TGFBR1 by the constitutively active TGFBR2.

Open Targets scores its association with cancer at 0.87 (direct and indirect evidence; datatypes genetic literature 0.61, affected pathway 0.87, literature 0.99, genetic association 0.85, somatic mutation 0.95, animal model 0.43). IntOGen calls it a driver in 14 cohorts (3 activating, 11 loss-of-function), covering Renal Clear Cell Carcinoma, Cervical Adenocarcinoma, Cervical Squamous Cell Carcinoma, Colorectal Adenocarcinoma, Oesophageal Adenocarcinoma, Head and Neck Squamous Cell Carcinoma and others.

- Biology: Transmembrane serine/threonine kinase forming with the TGF-beta type I serine/threonine kinase receptor, TGFBR1, the non-promiscuous receptor for the TGF-beta cytokines TGFB1, TGFB2 and TGFB3. Transduces the TGFB1, TGFB2 and TGFB3 signal from the cell surface to the cytoplasm and thus regulates a plethora of physiological and pathological processes including cell cycle arrest in epithelial and haematopoietic cells, control of mesenchymal cell proliferation and differentiation, wound healing, extracellular matrix production, immunosuppression and carcinogenesis. The formation of the receptor complex composed of 2 TGFBR1 and 2 TGFBR2 molecules symmetrically bound to the cytokine dimer results in the phosphorylation and activation of TGFBR1 by the constitutively active TGFBR2. Activated TGFBR1 phosphorylates SMAD2 which dissociates from the receptor and interacts with SMAD4. The SMAD2-SMAD4 complex is subsequently translocated to the nucleus where it modulates the transcription of the TGF-beta-regulated genes. This constitutes the canonical SMAD-dependent TGF-beta signalling cascade. Location: Cell membrane; Membrane raft; Secreted (UniProt). Locus 3p24.1 (HGNC).

## Notes

- Written by scripts/fetch-cancer-genes.ts from CIViC, Open Targets, IntOGen, HGNC and UniProt; the function text is UniProt's, condensed and in UK spelling. Roles: IntOGen calls it an activating (Act) driver in 3 cohorts; IntOGen calls it a loss-of-function (LoF) driver in 11 cohorts. Evidence tier "cohort-driver" is the strongest of those signals.
- Prevalence not recorded: none of the sources gives a positivity rate.
