DESCRIPTION

Also known as ITA6_HUMAN, ITGA6. Integrin alpha-6/beta-1 (ITGA6:ITGB1) is a receptor for laminin on platelets (By similarity). Integrin alpha-6/beta-1 (ITGA6:ITGB1) is present in oocytes and is involved in sperm-egg fusion (By similarity). 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 (By similarity). ITGA6:ITGB4 binds to NRG1 (via EGF domain) and this binding is essential for NRG1-ERBB signaling (PubMed:20682778). ITGA6:ITGB4 binds to IGF1 and this binding is essential for IGF1 signaling (PubMed:22351760). ITGA6:ITGB4 binds to IGF2 and this binding is essential for IGF2 signaling (PubMed:28873464). Heterodimer of an alpha and a beta subunit. The alpha subunit is composed of a heavy and a light chain linked by a disulfide bond (By similarity). Alpha-6 associates with either beta-1 (ITGB1) or beta-4 (ITGB4) to form ITGA6:ITGB1 and ITGA6:ITGB4, respectively (By similarity). ITGA6:ITGB1 is found in a complex with CD9; interaction takes place in oocytes and is involved in sperm-egg fusion (By similarity). ITGA6:ITGB4 is found in a ternary complex with NRG1 and ERBB3 (PubMed:20682778). ITGA6:ITGB4 is found in a ternary complex with IGF1 and IGF1R (PubMed:22351760). ITGA6:ITGB4 interacts with IGF2 (PubMed:28873464). Interacts with ADAM9 (By similarity). Interacts with RAB21 (PubMed:16754960). Interacts with MDK (PubMed:15466886). ITGA6:ITGB1 interacts with MDK; this interaction mediates MDK-induced neurite outgrowth (PubMed:15466886).
