Predicted to enable actin binding activity; anion binding activity; and protein kinase C binding activity. Predicted to be involved in several processes, including actin filament depolymerization; negative regulation of actin filament polymerization; and positive regulation of cell projection organization. Predicted to be located in several cellular components, including growth cone; lamellipodium; and stereocilium. Predicted to be active in actin filament and myofibril. Orthologous to human TWF2 (twinfilin actin binding protein 2); INTERACTS WITH 2,3,7,8-tetrachlorodibenzodioxine; 4,4'-sulfonyldiphenol; acetamide.
