Figure 1. — β_H is mislocalized in crumbs^8F105 embryos. (A) Schematic figure showing the organization of cell–cell junctions in the ectoderm of Drosophila. Arm, armadillo; SJ, septate junction; ZA, zonula adherens. Some key markers for the different structures are indicated. (B) Confocal micrographs showing part of the ectoderm from stage 11/12 embryos stained for β_H (bottom) and Crumbs (top). In WT embryos, β_H and Crumbs are highly concentrated in the apicolateral region of each cell (arrows). In crumbs^8F105 embryos (crb^8F105), β_H is mislocalized to the whole apical membrane (asterisks), and to a lesser extent to the cytoplasm. Bar, 5 μm.
