Reaction: RAC1 GAPs stimulate RAC1 GTPase activity

- in pathway: RAC1 GTPase cycle
The following GTPase activating proteins (GAPs) were shown to bind RAC1 and stimulate its GTPase activity, resulting in GTP to GDP hydrolysis and conversion of the active RAC1:GTP complex into the inactive RAC1:GDP complex (the high throughput screen by Bagci et al. 2020 examined binding of GAPs to constitutively active RAC1 mutant without testing for activation of RAC1 GTPase activity and is cited as supporting evidence, as indicated):
