Predicted to enable actin filament binding activity and beta-tubulin binding activity. Predicted to be involved in several processes, including barbed-end actin filament capping; regulation of cell morphogenesis; and regulation of plasma membrane bounded cell projection assembly. Predicted to act upstream of or within several processes, including actin polymerization or depolymerization; negative regulation of microtubule polymerization; and plasma membrane bounded cell projection organization. Located in dendritic spine and neuronal cell body. Biomarker of dementia. Orthologous to human CAPZB (capping actin protein of muscle Z-line subunit beta).
