Enables cytoskeletal protein binding activity. Involved in several processes, including cellular response to trichostatin A; positive regulation of dendritic spine morphogenesis; and response to ethanol. Located in lamellipodium; podosome core; and postsynaptic density. Is active in postsynapse. Orthologous to human ACTR2 (actin related protein 2). [provided by Alliance of Genome Resources, Apr 2022]
