A systematic analysis was carried out to identify the amino acid signals that regulate the nucleo-cytoplasmic transport of the influenza A virus nucleoprotein (NP). The analysis involved determining the intracellular localization of eight deleted recombinant NP proteins and 14 chimeric proteins containing the green fluorescent protein fused to different NP fragments. In addition, the subcellular distribution of NP derivatives that contained specific substitutions at serine-3, which is the major phosphorylation site of the A/Victoria/3/75 NP, were analysed. From the results obtained, it is concluded that the NP contains three signals involved in nuclear accumulation and two regions that cause cytoplasmic accumulation of the fusion proteins. One of the karyophilic signals was located at the N terminus of the protein, and the data obtained suggest that the functionality of this signal can be modified by phosphorylation at serine-3. These findings are discussed in the context of the transport of influenza virus ribonucleoprotein complexes into and out of the nucleus.

Peptide nucleic acid (PNA) is one of the most useful DNA analogs in a wide variety of gene analysis in human cells. In order to exhibit its maximal functions, PNA must be localized to a desired place (e.g., nucleus, cytoplasm and other organelles). Here, we introduced PNAs into HeLa cells by electroporation and examined their localization at various time points. The PNA which binds to the mitochondrial COII gene was initially accumulated in the nucleus, and thereafter mostly transferred to cytoplasm. This time-dependent intracellular localization of PNA is ascribed to the breakdown of the nuclear envelope in the cell division. On the other hand, another PNA that binds to telomere repeat sequence mostly remained in the nucleus, even after the cell division occurred. The retention of this PNA in the nucleus was further enhanced when it was conjugated with Cy3.
