Research Abstract

The NS2 protein of influenza A virus is thought to be required for nuclear export of viral ribonucleoprotein complexes. To determine the kinetics of the NS2 protein during viral replication, we introduced full-length Venus to the N terminus of the NS cDNA encoding the NS2 protein and generated Venus-tagged NS2 mutant virus by reverse genetics. Madin-Darby Canine Kidney cells were infected with the Venus-tagged NS2 mutant virus, and monitored by time-laps. Then we got dynamics image of the NS2 protein in a cell. NS2 protein was accumulated in the nucleus at the first stage of the infection and then burst to the cytoplasm. This Venus-tagged NS2 mutant virus will likely be useful for analysis of subcellular trafficking of the NS2 protein.
