| 摘要 |
The present invention relates to a novel method of genetic modification, wherein a nucleic acid of interest is transferred across a biological membrane, and/or directed to a specific location within or on a cell, by use of a synthetic transport entity. The transport entity according to the invention is new as such and produced by coupling a functional element (FE), such as a nuclear localization signal (NLS), an antennapedia peptide of a protein comprising both membrane translocation and nuclear transport properties, to a binding element (BE), such as a peptide nucleic acid (PNA), preferably separated by a linker molecule, which combination is then hybridized to a BE target sequence present on a carrier, which also includes the nucleic acid of interest. The present nucleic acid of interest may for example be a gene encoding a peptide, a protein or an RNA, or any other nucleic acid useful in genetic recombination events. |
