Summary: Enables protein heterodimerization activity. Contributes to extracellular matrix protein binding activity. Involved in several processes, including embryonic morphogenesis; imaginal disc morphogenesis; and open tracheal system development. Located in several cellular components, including costamere; focal adhesion; and synaptic membrane. Part of integrin complex. Is expressed in several structures, including epithelial cell; ganglia; gut section; imaginal disc; and somatic precursor cell. Human ortholog(s) of this gene implicated in several diseases, including amelogenesis imperfecta type 1H; autoimmune thrombocytopenic purpura; blood platelet disease (multiple); coronary artery disease (multiple); and leukocyte adhesion deficiency (multiple). Orthologous to several human genes including ITGB2 (integrin subunit beta 2). [provided by Alliance of Genome Resources, Apr 2025]
