Reaction: RAC1 GEFs activate RAC1

- in pathway: RAC1 GTPase cycle
The following guanine nucleotide exchange factors (GEFs) were shown to bind RAC1 and catalyze GDP to GTP exchange on RAC1, resulting in formation of the active RAC1:GTP complex (the high throughput study by Bagci et al. examined binding of GEFs to inactive RAC1 mutant without testing for RAC1-directed GEF activity and is cited as supporting evidence):
