ADF binds to both G-actin
and F-actin, enhances the turnover of actin filaments by
increasing depolymerisation at the pointed end and severs
existing filaments [55,56]. Since polymerisation at the barbed
end produces the force that is needed for propulsion, sufficient
available actin monomers are required for this polymerisation.
An enhanced turnover of actin filaments increases the number
of available actin monomers for polymerisation and thus the
rate of movement.
