Clues about polynucleotidyl transporters

["<p r e d a t o r>"]

Has anyone here any knowledge of port proteins (preferably ATP driven, not
voltage gated) which can transport dsDNA across *two* eukaryotic
membranes? Names pf the proteins (or accession nums) would be good.

Also, is there a half-decent reference anywhere about the mechanisms of
polynucleotide transport between mitochondria and the cell nucleus?
