ITGAV Membrane Protein Introduction

Introduction of ITGAV

Integrin alpha-V (ITGAV), which in humans is encoded by the ITGAV gene, is composed of an alpha chain and a beta chain. It binds to multiple integrin beta chains to form different integrins. In mammals ITGAV includes αVβ1, αVβ3, αVβ5, αVβ6, and αVβ8 subtypes. ITGAV is a heterodimeric integral membrane protein, which acts as a receptor for many proteins, involved in the cell signal transduction through recognition the sequence R-G-D in a wide array of ligands.

Function of ITGAV Membrane Protein

ITGAV is essential for a variety of cellular signaling pathways including NRG1-ERBB signaling, FGF1 signaling and IL1B signaling. In addition to mediating cell signal transduction, ITGAV also plays a crucial role in cell adhesion. Integrin forms membrane-associative adhesion complexes by recruiting adaptors and signaling proteins and finally plays a role in the classical pathway of adhesion signaling. Several diseases are associated with ITGAV, such as epithelial adhesion, proliferation, wound healing and cancer. Overexpression of the ITGAV gene has been associated with progression and spread of colorectal cancer and prostate cancer. Besides, integrin signaling is also important for the generation and maintenance of epidermis, the heterodimer consisting of alpha V and beta 3 subunits is also known as the vitronectin receptor. In conclusion, integrin regulates cell growth, survival, movement and differentiation through interaction with ECM, various intramembrane and intracellular molecules.
