Description
ARF1 (small GTP-binding ADP-ribosylation factor 1) is a member of the ARF family, which contains five other ARF proteins (1). ARF1 functions in various membrane trafficking events in the ER-Golgi system and in the maintenance of organelle structure. Inactive ARF1 (ARF1-GDP) localizes in the cytoplasm, while the active form (ARF1-GTP) localizes in the membrane (2-3). Active ARF1 is also localized to the Golgi complex by regulating the assembly of coat proteins onto membranes and mediating traffic in the ER-Golgi. ARF1 activates phospholipase D and phosphatidylinositol 4-phosphate 5-kinase and recruits COPI to membranes (4-5).
