Integrin alpha-6/beta-1 (ITGA6:ITGB1) is a receptor for laminin on platelets. Integrin alpha-6/beta-1 (ITGA6:ITGB1) is present in oocytes and is involved in sperm-egg fusion. Integrin alpha-6/beta-4 (ITGA6:ITGB4) is a receptor for laminin in epithelial cells and it plays a critical structural role in the hemidesmosome. ITGA6:ITGB4 binds to NRG1 (via EGF domain) and this binding is essential for NRG1-ERBB signaling. ITGA6:ITGB4 binds to IGF1 and this binding is essential for IGF1 signaling. ITGA6:ITGB4 binds to IGF2 and this binding is essential for IGF2 signaling.

alpha6 and beta1 integrins are induced in Schwann cells in the sciatic nerve after a crush injury, and the blocking of integrin activity by siRNA expression and by treatment with anti-integrin antibodies attenuates Schwann cell contact with cultured neurons and decreases neurite outgrowth. After nerve transection, the levels of alpha6 and beta1 integrins in the distal nerve stump are lower than corresponding nerve area...PMID:29223350
