Look for the papers of David Goldfarb.  He has done a lot of work on
nuclear localization.  If anyone has a vector he does, or knows who has
it.  One NLS he uses is a few amino acid peptide of SV40 large T--this has
the advantage that a single (defined) amino acid change renders it non-
functional.  You could easily construct oligos to act as linkers 
containing the + and - NLS and ligate them to your genes.  The sequences
of the NLS are in his papers.

Or you could write to
