RAB2 is part of the RAB family of small GTPases that regulate intracellular trafficking of membrane bound vesicles. It is highly conserved in eukaryotes, from C. elegans to humans. These GTPases influence the creation, movement, attachment, fusion, and destiny of vesicles originating in the endoplasmic reticulum (ER)/Golgi systems. Like other members of its family, RAB2
