Fig. 6.

Rap1, Cno and Mbt synergize with Baz to promote AJ accumulation at the plasma membrane. (A–A‴′) baz^xi106 mutant cells (lacking GFP, blue, the contour of which is denoted by the dashed line, A) and stained for Arm (A′), aPKC (A″) and Mbt (A‴). (B–B‴) mbt^P1, baz^xi106 double mutant cells (lacking GFP, blue, B) and stained for Arm (B′) and aPKC (B″). (C–C‴′) baz^xi106, Rap1IR double mutant cells (lacking GFP, blue, C) and stained for Arm (C′), aPKC (C″) and Mbt (C‴). (D) Confocal section of the cone and pigment cells in an mbt^P1; Rap1IR retina stained for Arm (green) and aPKC (red). (D′–D‴′) View of the delaminated photoreceptor proximal to D. (D′) Arm, (D″) aPKC, (D‴), merge (D″,D‴); a white-dashed rectangle highlights two ommatidia that are magnified in D‴′. The white arrows point to ZA domains between flanking photoreceptors. (E) Quantification of the percentage of pairs of photoreceptors sharing a lateral Arm domain in wild-type, mbt^P1, Rap1IR, baz ^xi106, double mbt^P1; Rap1IR, double baz ^xi106; Rap1IR and double baz ^xi106, mbt^P1 cells. Results are mean±s.e.m. (n≥180 from 5 retinas). Scale bars: 4 μm.
