Predicted to enable actin filament binding activity and microfilament motor activity. Predicted to be involved in actin filament organization and vesicle transport along actin filament. Predicted to be part of myosin complex. Predicted to be active in several cellular components, including actin cytoskeleton; microvillus; and vesicle. Is expressed in several structures, including alimentary system; gonad; nervous system; neural retina; and respiratory system. Orthologous to human MYO1H (myosin IH).
