We observed mostly cytoplasmic, some nuclear, but rarely both, GFP 
fluorescence in RAT2 fibroblasts transfected with the pGreenLantern GFP 
construct (no NLS). The fibroblasts were FACs sorted 2 weeks after 
transfection and it was pretty surprising to see some clones expressing 
it in the nucleus and others (more as one would expect) in the cytoplasm.
Just an observation..... not a publication.......   :)
