Summary of TGFBR2

The TGFBR2 gene encodes a protein called transforming growth factor-beta (TGF-β) receptor type 2. It transmits signals from the cell surface into the cell and affects activities inside the cell such as stimulation of cell growth and division. Because TGF-β receptor type 2 keeps cells from growing and dividing too rapidl, it is also important in suppressing the formation of tumors (R).

The Function of TGFBR2

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 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 TGFRB1 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.

Advanced Summary

     familial thoracic aortic aneurysm and dissection At least nine TGFBR2 gene mutations have been identified in people with familial thoracic aortic aneurysm and dissection (familial TAAD). This disorder involves problems with the aorta, which is the large blood vessel that distributes blood from the heart to the rest of the body. The aorta can weaken and stretch, causing a bulge in the blood vessel wall (an aneurysm). Stretching of the aorta may also lead to a sudden tearing of the layers in the aorta wall (aortic dissection). Aortic aneurysm and dissection can cause life-threatening internal bleeding. The TGFBR2 gene mutations that cause familial TAAD disturb signal transduction. The disturbed signaling can impair cell growth and development. It is not known how these changes result in the specific aortic abnormalities associated with familial TAAD. Loeys-Dietz syndrome More than 80 mutations in the TGFBR2 gene have been found to cause Loeys-Dietz syndrome type II. Loeys-Dietz syndrome affects connective tissue, which gives structure and support to blood vessels, the skeleton, and other parts of the body. This type of Loeys-Dietz syndrome is characterized by blood vessel abnormalities and skeletal deformities. Most TGFBR2 gene mutations that cause Loeys-Dietz syndrome change single protein building blocks (amino acids) in TGF-β receptor type 2, resulting in a receptor with little or no function. Although the receptor has severely reduced function, cell signaling occurs at an even greater intensity than normal. Researchers speculate that the activity of proteins in this signaling pathway is increased to compensate for the reduction in TGF-β receptor type 2 activity; however the exact mechanism responsible for the increase in signaling is unclear. The overactive signaling pathway disrupts development of connective tissue and various body systems and leads to the varied signs and symptoms of Loeys-Dietz syndrome type II. Some TGFBR2 gene mutations that cause Loeys-Dietz syndrome type II have also been found to cause familial TAAD (described above). Affected families can include some individuals with Loeys-Dietz syndrome and others with familial TAAD. cancers Some TGFBR2 gene mutations are acquired during a person's lifetime and are present only in certain cells. These changes are called somatic mutations and are not inherited. People with somatic mutations in the TGFBR2 gene appear to have an increased risk of developing various cancers. Somatic TGFBR2 gene mutations probably disrupt the signaling process that helps regulate cell division. Unchecked cell division can lead to the formation of tumors, particularly when TGFBR2 gene mutations occur in the colon, rectum, and esophagus. It is estimated that 30 percent of cancerous (malignant) colon tumors have TGFBR2 gene mutations in their cells.

     The TGFBR2 gene provides instructions for making a protein called transforming growth factor-beta (TGF-β) receptor type 2. This receptor transmits signals from the cell surface into the cell through a process called signal transduction. Through this type of signaling, the environment outside the cell affects activities inside the cell such as stimulation of cell growth and division. To carry out its signaling function, the TGF-β receptor type 2 spans the cell membrane, so that one end of the protein projects from the outer surface of the cell (the extracellular domain) and the other end remains inside the cell (the intracellular domain). A protein called TGF-β attaches (binds) to the extracellular domain of the TGF-β receptor type 2, which turns on (activates) the receptor and allows it to bind to a similar receptor on the cell surface. These three proteins form a complex, which triggers signal transduction by activating other proteins in this signaling pathway. Signals triggered through the TGF-β receptor complex prompt various responses by the cell, including the growth and division (proliferation) of cells, the maturation of cells to carry out specific functions (differentiation), cell movement (motility), and controlled cell death (apoptosis). Because TGF-β receptor type 2 keeps cells from growing and dividing too rapidly or in an uncontrolled way, it is also important in suppressing the formation of tumors.
