Enables cytoskeletal protein binding activity and identical protein binding activity. Involved in several processes, including plasma membrane tubulation; positive regulation of cellular component organization; and postsynaptic actin cytoskeleton organization. Located in Golgi membrane; cell leading edge; and cytoplasmic vesicle. Is active in glutamatergic synapse and postsynapse. Orthologous to human WASL (WASP like actin nucleation promoting factor).
