FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] The gene encodes a member of the integrin alpha chain family of proteins. Integrins are heterodimeric integral membrane proteins composed of an alpha chain and a beta chain that function in cell surface adhesion and signaling. The encoded preproprotein is proteolytically processed to generate light and heavy chains that comprise the alpha 4 subunit. This subunit associates with a beta 1 or beta 7 subunit to form an integrin that may play a role in cell motility and migration. This integrin is a therapeutic target for the treatment of multiple sclerosis, Crohn's disease and inflammatory bowel disease. Alternative splicing results in multiple transcript variants.

PHENOTYPE: Mice homozygous for disruptions in this gene exhibit embryonic lethality either due to failure of chorioallantoic fusion or cardiac abnormalities, including hemorrhage around the heart and defects in epicardium formation. [provided by MGI curators]
