SUBCELLULAR LOCALIZATION	intracellular
	intracellular,cytoplasm,cytosolic
	intracellular,cytoplasm,cytoskeleton

basic FUNCTION	involved in the regulation of growth of the actin filament by capping the barbed end of growing actin filaments
	CAPZB and PDE8B have been linked to TSH levels
	is an actin-capping protein that caps the growing end of F-actin and modulates the cytoskeleton and tethers actin filaments to the Z-line of the sarcomere in muscles
	actin filament length regulators CFL1, CAPZB and DIAPH1 regulate mitotic cortex thickness and both increasing and decreasing thickness decreases tension in mitosis
