WebAug 1, 2013 · Rabs are activated by specific guanine nucleotide exchange factors (GEFs) 1 that stimulate the release of GDP and the binding of GTP. Bound GTP is then hydrolyzed by the intrinsic Rab-GTPase activity of Rabs, which is activated by GTPase-activating proteins (GAPs), the enhancers of Rab-GTPase activity. Webthe role of Rab GTP-ases in Golgi organization and func-tion.44,64,73 Our goalhere is to summarize and discuss the recent literature on this topic. We will distinguish three groups of Rabs, those associated to the cis-side of the Golgi complex/intermediate compartment (IC), those associated towards the late Golgi/TGN/post-Golgi/
