Itga4 - integrin subunit alpha 4

Enables cell adhesion molecule binding activity; fibronectin binding activity; and protein antigen binding activity. Involved in several processes, including clathrin-dependent extracellular exosome endocytosis; neuron projection morphogenesis; and regulation of leukocyte migration. Located in several cellular components, including extracellular exosome; growth cone; and neuronal cell body. Used to study anti-basement membrane glomerulonephritis; diabetic retinopathy; nephritis; and pneumonia. Biomarker of pre-eclampsia. Human ortholog(s) of this gene implicated in autism spectrum disorder and pancreatic cancer. Orthologous to human ITGA4 (integrin subunit alpha 4). [provided by Alliance of Genome Resources, Apr 2022]
