STRN and carcinoma: Localization studies of striatin with α- and β-catenin, with other AJ markers and with desmosomal molecules have also been performed on cell culture monolayers, including epithelium or carcinoma-derived cells and cardiomyocyte-derived cells (for biochemical demonstrations of the presence of striatins in such cells, see Fig. 1a, b and Electronic supplementary material, Fig. S1; for immunofluorescence microscopy, see Electronic supplementary material, Figs. S7–S10).
