Abstract:King's College London, SE1 1UL.Actin cytoskeleton is composed of functionally distinct pools of filamentous (F)-actin defined by their regulatory machinery and dynamics. Although these networks may compete for actin monomers and regulatory factors [1][2][3][4] , the interaction between them remains poorly understood. Here, we show that disruption of the labile F-actin pool in neurons by limited actin depolymerization 5,6 unexpectedly triggers rapid enhancement of the F-actin content at the dendritic spine.
