Figure 4. Determination the presμmed NES function of UL2. (A) Schematic representation of WT UL2 and its deletion mutants UL2(225-277), UL2(278-334) and UL2(225-240) fused with EYFP. (B) Subcellular localization of these UL2 deletion mutants (shown in A) in plasmid-transfected live COS-7 cells. All scale bars indicate 10 μm.
