TGFBI

Protein-coding gene in the species Homo sapiens From Wikipedia, the free encyclopedia

Transforming growth factor, beta-induced, 68kDa, also known as TGFBI (initially called BIGH3, BIG-H3), is a protein which in humans is encoded by the TGFBI gene, locus 5q31.[5][6]

Function

This gene encodes an RGD-containing protein that binds to type I, II and IV collagens. The RGD motif is found in many extracellular matrix proteins modulating cell adhesion and serves as a ligand recognition sequence for several integrins. This protein plays a role in cell-collagen interactions and may be involved in endochondrial bone formation in cartilage. The protein is induced by transforming growth factor-beta and acts to inhibit cell adhesion.[5]

Clinical significance

Mutations of the gene cause several forms of corneal dystrophies.[7][8]
