Predicted to enable actin filament binding activity. Predicted to be involved in Arp2/3 complex-mediated actin nucleation and cell migration. Is active in glutamatergic synapse. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; immune system; and integumental system. Orthologous to human ARPC5L (actin related protein 2/3 complex subunit 5 like).
