Summary: Enables transmembrane signaling receptor activity. Involved in several processes, including cell-cell adhesion mediated by integrin; generation of neurons; and nematode male tail tip morphogenesis. Located in phagocytic cup. Part of integrin complex. Is expressed in several structures, including ABplaapppp; hermaphrodite gonad; neurons; ventral nerve cord; and vulE. Used to study cancer and epilepsy. Human ortholog(s) of this gene implicated in Duchenne muscular dystrophy; congenital muscular dystrophy due to integrin alpha-7 deficiency; junctional epidermolysis bullosa; junctional epidermolysis bullosa with pyloric atresia; and muscular disease. Orthologous to several human genes including ITGA6 (integrin subunit alpha 6). [provided by Alliance of Genome Resources, Dec 2024]
