Enables actin filament binding activity and protein domain specific binding activity. Involved in neuron projection morphogenesis; podosome assembly; and synapse assembly. Acts upstream of or within Rac protein signal transduction. Located in several cellular components, including lamellipodium; podosome; and ruffle. Is expressed in several structures, including central nervous system; genitourinary system; liver; retina; and spleen. Orthologous to human DBNL (drebrin like).
