Summary
Enables ATP hydrolysis activity. A structural constituent of cytoskeleton. Involved in several processes, including ascospore wall assembly; mitotic actomyosin contractile ring contraction; and vacuole inheritance. Located in actin cytoskeleton. Part of Ino80 complex; NuA4 histone acetyltransferase complex; and Swr1 complex. Used to study several diseases, including Baraitser-Winter syndrome 1; artery disease (multiple); autosomal dominant nonsyndromic deafness 20; intestinal atresia; and patent ductus arteriosus. Human ortholog(s) of this gene implicated in several diseases, including Baraitser-Winter syndrome 1; artery disease (multiple); congenital myopathy (multiple); intrinsic cardiomyopathy (multiple); and male infertility (multiple). Orthologous to several human genes including ACTA1 (actin alpha 1, skeletal muscle); ACTC1 (actin alpha cardiac muscle 1); and ACTB (actin beta). [provided by Alliance of Genome Resources, Jul 2025]
