Applications
Inhibition of actin depolymerization;
Stabilization of actin filaments.
Description
Phalloidin binds to actin filaments and inhibits their depolymerization by specific interaction at the interface of adjacent monomers of the filaments. Phalloidin is a bicyclic heptapeptide with high affinity for actin filaments and lower affinity for actin monomers. Binding of Phalloidin leads to a decrease in the rate constant for the dissociation of actin monmers from filament ends. This results in a stabilization of filaments, used in many assays where stable actin filaments are demanded.
Phalloidin is also inhibits the ATP-ase activity of F-actin. Binding arrests actin monomers in a specific G-actin state and stabilizes filament structure by strongly reducing the rate constant for monomer dissociation, an event associated with the trapping of ADP.
