Reaction: CDC42 GAPs stimulate CDC42 GTPase activity

- in pathway: CDC42 GTPase cycle
The following GTPase activating proteins (GAPs) were shown to bind CDC42 and stimulate its GTPase activity, resulting in GTP to GDP hydrolysis and conversion of the active CDC42:GTP complex into the inactive CDC42:GDP complex (the high throughput screen by Bagci et al. 2020 is cited as supporting evidence since it examined binding of GAPs to constitutively active CDC42 mutant but did not test for activation of CDC42 GTPase activity):
