ITGA5

ITGA5 Gene Summary

The product of this gene belongs to the integrin alpha chain family. Integrins are heterodimeric integral membrane proteins composed of an alpha subunit and a beta subunit that function in cell surface adhesion and signaling. The encoded preproprotein is proteolytically processed to generate light and heavy chains that comprise the alpha 5 subunit. This subunit associates with the beta 1 subunit to form a fibronectin receptor. This integrin may promote tumor invasion, and higher expression of this gene may be correlated with shorter survival time in lung cancer patients. Note that the integrin alpha 5 and integrin alpha V subunits are encoded by distinct genes. [provided by RefSeq, Oct 2015]

Protein Domains

A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
  • extracellular domain
  • signaling receptor activity
  • cell adhesion molecule binding
  • epidermal growth factor receptor binding
  • platelet-derived growth factor receptor binding
  • calcium ion binding
  • protein binding
  • vascular endothelial growth factor receptor binding
  • FG-GAP-like repeat
  • GFFKR motif
  • Integrin alpha (beta-propellor repeats)
  • Integrin alpha
