Rab GTPases comprise the largest member of the Ras superfamily with over 60 proteins in mammalian cells. 1 Following prenylation of C-terminally situated cysteine residues, active (GTP-bound) Rabs migrate to distinct subcellular compartments. The nucleotide-bound state of Rabs is regulated by GTPase …
