Gwl contains two essential NLS motifs in its central region. (A) The central region of Gwl is necessary and sufficient for nuclear localization. D-Mel cells expressing the indicated truncations of Gwl tagged with Myc were examined by immunofluorescence on a confocal microscope. Identified NLS motifs are shown. Bar, 5 µm. (B and C) Mutation of both NLSs (NLSmut = K518M, K520M [in NLS1] + K564M, R566L [in NLS2; see Fig. S2]) prevents the nuclear localization of Gwl. Immunofluorescence in D-Mel cells (B) and in syncytial embryos (C) expressing the indicated proteins. Bars, 10 µm.
