Immunolabeling of mutant proteins in HeLa cells. All three mutants shown here (Cx50D3E, Cx50G8E, and Cx50GNI) were able to reach the cell surface and cell-cell interfaces (arrows). Intracellular fluorescent signals were also detected. The cellular localization of these mutants was indistinguishable from that of the wild-type Cx50. Nuclei were labeled with DAPI (blue). Phase-contrast images (right) show cell morphology. Scale bar, 20 μm.
