Background

Wiskostatin is an N-WASP inhibitor, with an IC50 value slightly less than 10 μM. Wiskostatin interacts with a cleft in the regulatory GTPase-binding domain (GBD) of N-WASP and maintains N-WASP in an inactive conformation, thereby inhibiting Cdc42 and phosphatidylinositol 4,5-bisphosphate (PIP2) mediated N-WASP activation, as well as Arp2/3 complex activation. N-WASP, highly expressed in the brain, belongs to the WASP family in which member proteins initiate the nucleation of new actin filaments through activation of the Arp2/3 complex, and thus are emerging as critical regulators of the actin cytoskeleton. By inhibiting N-WASP, wiskostatin has been shown to interfere with the formation of dendritic spines and synapses in neurons.?

Reaction Conditions

2 or 5 μM wiskostatin

Applications

Wiskostatin caused a dose-dependent decrease in the number of dendritic spines and excitatory synapses. However, wiskostatin, even at the highest concentration (5 μM), did not significantly affect the number of inhibitory synapses. In addition, wiskostatin did not adversely affect the health of the neurons, because they were observed to develop normally and no detectable effects on the growth of axons or dendrites were seen at any of the wiskostatin concentrations used.
