Figure 5From: Inhibition of HIV-1 integrase nuclear import and replication by a peptide bearing integrase putative nuclear localization signalIN interaction as observed by the BiFC assay system. EGY48 yeast cells were transformed using the lithium acetate method with plasmids encoding the following combinations: GN-IN and GC-IN, GN-IN and GC-LEDGF, GN-IN and GC-linker (control), GN-IN and GC-Impα (importin α), GN-180-IN and GC-Impα, GN-NLS-IN and GC-Impα, GN-152-IN and GC-Impα, GN-IN and GC-Impβ (importin β), GN-Rev (HIV-1) and GC-Impα. Restoration of GFP fluorescence was observed by confocal microscopy. All other experimental conditions were as described in Methods. Bar 10 μm.Back to article page
