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.
