Abstract

The invention provides a cell-specific nuclear targeting molecule having a nucleic acid sequence which includes a binding site for a nuclear DNA binding protein expressed only in a specific cell type. The invention further provides a plasmid for targeting a DNA molecule into the nuclei of a specific cell type. The plasmid comprises the cell-specific nuclear targeting molecule and a DNA molecule to be targeted to the nuclei of the specific cell type. This plasmid of the subject invention can be introduced into various host cells, and the cell-specific nuclear targeting molecule will target the DNA molecule to the nuclei of the specific cell type. Thus, the invention further provides a method of targeting a DNA molecule into the nuclei of a specific cell type. The method comprises providing a plasmid (the plasmid comprising the cell-specific nuclear targeting molecule and the DNA molecule to be targeted) and introducing the plasmid into the cytoplasm of the specific cell type. In this method, the cell-specific nuclear targeting molecule targets the DNA molecule into the nuclei of the specific cell type.
