Function

Transmembrane serine/threonine kinase forming with the TGF-beta type II serine/threonine kinase receptor, TGFBR2, 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 is thus regulating a plethora of physiological and pathological processes including cell cycle arrest in epithelial and hematopoietic 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 the 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 signaling cascade. Also involved in non- canonical, SMAD-independent TGF-beta signaling pathways. For instance, TGFBR1 induces TRAF6 autoubiquitination which in turn results in MAP3K7 ubiquitination and activation to trigger apoptosis. Also regulates epithelial to mesenchymal transition through a SMAD-independent signaling pathway through PARD6A phosphorylation and activation. {ECO:0000269PubMed:15761148, ECO:0000269PubMed:16754747, ECO:0000269PubMed:18758450, ECO:0000269PubMed:7774578, ECO:0000269PubMed:8752209, ECO:0000269PubMed:8980228, ECO:0000269PubMed:9346908}.

Disease Associations

Loeys-Dietz syndrome 1 (LDS1) [MIM:609192]: An aortic aneurysm syndrome with widespread systemic involvement, characterized by arterial tortuosity and aneurysms, hypertelorism, and bifid uvula or cleft palate. Physical findings include prominent joint laxity, easy bruising, wide and atrophic scars, velvety and translucent skin with easily visible veins, spontaneous rupture of the spleen or bowel, and catastrophic complications of pregnancy, including rupture of the gravid uterus and the arteries, either during pregnancy or in the immediate postpartum period. Some patients have craniosynostosis, exotropy, micrognathia and retrognathia, structural brain abnormalities, and intellectual deficit. {ECO:0000269PubMed:15731757, ECO:0000269PubMed:16596670, ECO:0000269PubMed:16791849, ECO:0000269PubMed:16928994, ECO:0000269PubMed:19883511, ECO:0000269PubMed:22113417}. Note=The disease is caused by mutations affecting the gene represented in this entry. TGFBR1 mutation Gln-487 has been reported to be associated with thoracic aortic aneurysms and dissection (TAAD) (PubMed:16791849). This phenotype, also known as thoracic aortic aneurysms type 5 (AAT5), is distinguised from LDS1 by having aneurysms restricted to thoracic aorta. It is unclear, however, if this condition is fulfilled in individuals bearing Gln-487 mutation, that is why they are considered as LDS1 by the OMIM resource. {ECO:0000269PubMed:16791849}.Multiple self-healing squamous epithelioma (MSSE) [MIM:132800]: A disorder characterized by multiple skin tumors that undergo spontaneous regression. Tumors appear most often on sun-exposed regions, are locally invasive, and undergo spontaneous resolution over a period of months leaving pitted scars. {ECO:0000269PubMed:21358634}. Note=The disease is caused by mutations affecting the gene represented in this entry.
