Predicted to enable actin filament binding activity and phosphatidylinositol-4,5-bisphosphate binding activity. Predicted to be involved in several processes, including actin filament severing; actin polymerization or depolymerization; and barbed-end actin filament capping. Predicted to be active in actin cytoskeleton and cytoplasm. Is expressed in several structures, including central nervous system; cornea; hatching gland; pancreatic system; and swim bladder.
