Integrin alpha-3 is a protein that in humans is encoded by the ITGA3 gene.[1][2] 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[edit]

The alpha 3 beta 1 integrin is known variously as: very late (activation) antigen 3 ('VLA-3'), very common antigen 2 ('VCA-2'), extracellular matrix receptor 1 ('ECMR1'), and galactoprotein b3 ('GAPB3').[3]

Interactions[edit]

CD49c has been shown to interact with TSPAN4,[4] LGALS8,[5] CD9[6][7] and FHL2.[8]
