GFP localization ?

When transfecting 293HEK and NIH 3T3 MF-cells with GFP (humanized
S65T in pCDNA3) I noticed the brightest fluorescence in the nucleus,
while a (certain) fusion protein doesn't. Is there a reason for this?
Actually, I had expected that there was no fluorescence in the
nucleus since there's no nuclear import sequence. Am I wrong? Is
there resonance energy transfer from DNA to GFP?
The phenomenon occurs when using a Hg lamp with filters for FITC as
well as a 488nm argon laser and a confocal microscope.
