WebRab proteins represent the largest branch of the Ras-like small GTPase superfamily and there are 66 Rab genes in the human genome. They alternate between GTP- and GDP-bound states, which are facilitated by guanine nucleotide exchange factors (GEFs) and GTPase-activating proteins (GAPs), and function as molecular switches in regulation of … WebA second example of coordinated activation is suggested by interactions between exocytic Ypts and Arf GEFs. Arfs belong to a different family of Ras-like GTPases that have been shown to play a role in coat assembly during vesicle formation. Like other GTPases, Arfs have specific activating GEFs . The exocytic Ypts, Ypt1 and Ypt31/Ypt32 and the ...
