Mechanism of celluar import mediated by nuclear localization signals / 中国药理学通报

ABSTRACT

Some basic nuclear localization signals(NLS) have the capability of penetrating cell membrane and deliverying recombinant proteins, DNA, oligonucleotide into living cells. NLS based delivery system prohaps can satisfy most of major requirement in cargoing exogenous macromolecules or charged compounds. Different internalization mechanisms were found for different NLSs. Endocytosis or electrostatic binding of the anionic membranes and cationic NLSs probably induce celluar uptake.
