Synergy between Cyclase-associated protein and Cofilin accelerates actin filament depolymerization by two orders of magnitude
Abstract
Cellular actin networks can be rapidly disassembled and remodeled in a few seconds, yet in vitro actin filaments depolymerize over minutes. Here the authors show that Cyclase-associated protein (CAP) and Cofilin synergize to processively depolymerize actin filament pointed ends 330-fold faster than spontaneous depolymerization.
