beta6

Integrin beta-6 is a protein that in humans is encoded by the ITGB6 gene. It is the β6 subunit of the integrin αvβ6. Integrins are αβ heterodimeric glycoproteins which span the cell’s membrane, integrating the outside and inside of the cell. Integrins bind to specific extracellular proteins in the extracellular matrix or on other cells and subsequently transduce signals intracellularly to affect cell behaviour. One α and one β subunit associates non-covalently to form 24 unique integrins found in mammals. While some β integrins subunits partner with multiple a subunits, β6 associates exclusively with the av subunit. Thus, the function of ITGB6 is entirely associated with the integrin αvβ6.
