Predicted to enable actin filament binding activity and microfilament motor activity. Acts upstream of or within glomerulus development. Predicted to be located in stereocilium membrane. Predicted to be part of myosin complex. Predicted to be active in several cellular components, including actin cytoskeleton; microvillus; and plasma membrane. Is expressed in several structures, including digestive system; head; notochord; pectoral fin; and pronephric glomerulus. Orthologous to human MYO1C (myosin IC).
