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 act upstream of or within several processes, including defense response to Gram-positive bacterium; neutrophil degranulation; and positive regulation of cell migration. Predicted to be located in cortical actin cytoskeleton and cytosol. Predicted to be part of filamentous actin. Predicted to be active in several cellular components, including actin cytoskeleton; microvillus; and vesicle. Orthologous to human MYO1F (myosin IF).
