Rab small GTPases regulate vesicle transport in eukaryotes by interacting with various effectors. Guanine nucleotide-exchange factor (GEF) catalyzes the transition from inactive GDP-bound Rab to active GTP-bound Rab. The existence of several GDP-bound intermediates containing the Arabidopsis thaliana Rab5 homologue
