Predicted to enable actin filament binding activity. Predicted to be involved in actin cytoskeleton organization; barbed-end actin filament capping; and cell junction assembly. Predicted to be located in several cellular components, including brush border; cell-cell junction; and cortical cytoskeleton. Predicted to be part of F-actin capping protein complex and WASH complex. Orthologous to human CAPZA1 (capping actin protein of muscle Z-line subunit alpha 1).
