F-actin capping protein (CapZ) regulates growth of actin filaments by capping the barbed end of the growing filament thus blocking the exchange of subunits at this end. CapZ is a heterodimer with α and β subunits[1]. For more details see Group:MUZIC:CapZ.

F-actin capping protein α (grey) and β subunits (green) complex with ethanosulfonic acid and Ba+2 ion (PDB code 3aa7)
