CAPZA2 polyclonal antibody

The F-Actin family of capping proteins includes CapZ-α1, CapZ-α2, CapZ-α3 and CapZ-β3, all of which function in a calcium-dependent manner and bind to the fast growing barbed end of Actin filaments, thereby blocking protein exchange at these ends. The F-Actin capping protein complex is a heterodimer consisting of α and β subunits that caps the barbed ends of Actin filaments and nucleates the polymerization of Actin monomers, yet does not sever Actin filaments.
