What is the official name of the TGFBR1 gene?
The official name of this gene is “transforming growth factor beta receptor I.”
TGFBR1 is the gene's official symbol. The TGFBR1 gene is also known by other names, listed below.

What is the normal function of the TGFBR1 gene?
The TGFBR1 gene provides instructions for making a protein called transforming growth factor-beta (TGF-β) receptor type 1. 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, TGF-β receptor type 1 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 TGF-β receptor type 1, 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 1 keeps cells from growing and dividing too rapidly or in an uncontrolled way, it is also important in suppressing the formation of tumors.
