    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
