Expression analysis of bpNLS-1 and bpNLS-2. bpNLS-1R and bpNLS-2R (with R105) localizes predominantly to the nucleus. Note that the bpNLS-1M (with M105) exhibits a predominantly cytoplasmic localization pattern but also localizes to the nucleus as well. Arrows indicate a dividing cell with two daughter nuclei and the bpNLS-1M demonstrating an exclusive cytoplasmic localization. bpNLS-2M (with M105) localizes to the cytoplasm.
