Predicted to enable actin filament binding activity and phosphatidylinositol-4,5-bisphosphate binding activity. Predicted to be involved in actin filament severing; actin polymerization or depolymerization; and barbed-end actin filament capping. Predicted to act upstream of or within cytoskeleton organization. Predicted to be active in actin cytoskeleton and cytoplasm. Is expressed in several structures, including adaxial cell; cardiovascular system; musculature system; optic vesicle; and sensory system. Human ortholog(s) of this gene implicated in myofibrillar myopathy 10. Orthologous to human SVIL (supervillin).
