FRAP of Nrx IV-GFP in embryonic epithelial cells. Side (A) and face-on (B) views of wild-type embryos, side (C) and face-on (D) views of Dfvari embryos at stage15. Face-on (E) and side (F) views of cora mutant embryos. Pre-bleach images are shown on the left. The bleached areas are indicated with boxes. Images on the right show the recovery of fluorescence 160 seconds after bleaching. Bar: 5 μm in A-E and F. Schematic representation of the distribution of septate junction components, Nrx IV, Vari and Cora in each genotype.
