Dissection of a novel nuclear localization signal in open reading frame 29 of varicella-zoster virus.
Open reading frame 29 (ORF29) of varicella-zoster virus (VZV) encodes a 120-kDa single-stranded DNA binding protein (ORF29p) that is not packaged in the virion and is expressed during latency. During lytic infection, ORF29p is localized primarily to infected cell nuclei. In contrast, ORF29p is found exclusively in the cytoplasm in neurons of the dorsal root ganglia obtained at autopsy from sero...
متن کاملNuclear-localization-signal-dependent and nuclear-export-signal-dependent mechanisms determine the localization of 5-lipoxygenase.
5-Lipoxygenase (5-LO) metabolizes arachidonic acid to leukotriene A4, a key intermediate in leukotriene biosynthesis. To explore the molecular mechanisms of its cell-specific localization, a fusion protein between green fluorescent protein (GFP) and human 5-LO (GFP-5LO) was expressed in various cells. GFP-5LO was localized in the cytosol in HL-60 cells and in both the nucleus and the cytosol in...
متن کاملAnalysis of a developmentally regulated nuclear localization signal in Xenopus
The 289 residue nuclear oncoprotein encoded by the adenovirus 5 Ela gene contains two peptide sequences that behave as nuclear localization signals (NLS). One signal, located at the carboxy terminus, is like many other known NLSs in that it consists of a short stretch of basic residues (KRPRP) and is constitutively active in cells. The second signal resides within an internal 45 residue region ...
متن کاملA nuclear localization signal binding protein in the nucleolus
We used functional wild-type and mutant synthetic nuclear localization signal peptides of SV-40 T antigen cross-linked to human serum albumin (peptide conjugates) to assay their binding to proteins of rat liver nuclei on Western blots. Proteins of 140 and 55 kD (p140 and p55) were exclusively recognized by wild-type peptide conjugates. Free wild-type peptides competed for the wild-type peptide ...
متن کاملA Ty1 integrase nuclear localization signal required for retrotransposition.
Ty1 retrotransposition in Saccharomyces cerevisiae requires integrase (IN)-mediated insertion of Ty1 cDNA into the host genome. The transposition components are assembled in the cytoplasm and must cross the nuclear envelope to reach the genomic target, since, unlike animal cell nuclear membranes, the yeast cell nuclear membrane remains intact throughout the cell cycle. We have identified a bipa...
