Integrin alpha 3
Integrin alpha-3 is a protein that in humans is encoded by the ITGA3 gene.
ITGA3 is an integrin alpha subunit. Together with beta-1 subunit, it makes up half of the α3β1 integrin duplex that plays a role in neural migration and corticogenesis, acted upon by such factors as netrin-1 and reelin.
ITGA3 encodes the integrin alpha 3 chain. Integrins are heterodimeric integral membrane proteins composed of an alpha chain and a beta chain. Alpha chain 3 undergoes post-translational cleavage in the extracellular domain to yield disulfide-linked light and heavy chains that join with beta 1 to form an integrin that interacts with many extracellular matrix proteins.Alternative names
The alpha 3 beta 1 integrin is known variously as: very late antigen 3, very common antigen 2, extracellular matrix receptor 1, and galactoprotein b3.Interactions
