Abstract (english)
Arf proteins are small GTP-binding proteins (GTPases) that are one of the main regulators of endocytosis and intracellular trafficking. They function as molecular switches, meaning that they continuously cycle between active (GTP) and inactive (GDP) form. When activated they bind to the membranes of endosomal compartments where they recruit their effector molecules. We have previously shown that Arf GTPases have important role in pathogenesis of murine cytomegalovirus (MCMV) infection. While Arf1 and Arf6 are important for the establishment of MCMV infection, Arf3 and Arf4 have important role in biogenesis of virion assembly compartment. The aim of this study was to determine the degree of Arf GTPases activation during MCMV infection. For that purpose, Balb 3T3 cells were infected with ∆m138 MCMV and at 0, 6, 16 and 30 hours post infection degree of Arf GTPases activation was determined by 3 different methods: subcellular fractionation, precipitation of Arf proteins with GGA3 PBD agarose beads and by analysing intracellular localization of Arf effector molecules. Our results have shown that the main effector molecules of Arf proteins are accumulated in the juxtanuclear area of MCMV infected cells with a pattern like that of the Arf proteins. Furthermore, the proportion of Arf proteins that are precipitated with GGA3 PBD agarose beads increases with progression of MCMV infection, suggesting that Arf proteins are overactivated during MCMV infection, although we did not observe an increase in membrane fraction of Arf proteins.
