    Summary
    Enables actin filament binding activity. Involved in barbed-end actin filament capping. Located in cellular bud tip; cortical actin cytoskeleton; and incipient cellular bud site. Part of F-actin capping protein complex. Orthologous to human CAPZA1 (capping actin protein of muscle Z-line subunit alpha 1); CAPZA2 (capping actin protein of muscle Z-line subunit alpha 2); and CAPZA3 (capping actin protein of muscle Z-line subunit alpha 3).
