NOL7 requires cytosolic factors for efficient nuclear localization. HeLa cells permeabilized with digitonin were incubated at 4°C or 37°C as indicated with (+) or without (-) full length NOL7 expressing a C-terminal GFP tag, cytosol, heat-inactivated cytosol, ATP, or WGA. Localization of NOL7 was confirmed by visualization of GFP.
