Figure Lengend Snippet: (A) Schematic of frontal depiction of the wing pouch of the wing disc with the A (gray) and P (green) compartments indicated by gray and green, respectively; boxes indicate positions of (F-K) images. (B) White dotted lines delineate wing pouch and compartment border of disc expressing BAC encoded Hh:GFP. (C) Sagittal section of the wing disc expressing BAC encoded Hh:GFP (α-GFP antibody staining). Septate junction stained with α-DLG (red) marks septate junction; phalloidin marks adherens junction (blue). (D) Graph of Hh:GFP fluorescence in A and P compartments. (E) Schematic of sagittal wing pouch section with apical and basolateral compartments, Hh:GFP (green) and Rab7 (red) indicated. (F-G”) Frontal views of region of the A compartment of wing discs with BAC-encoded Hh:GFP detected with α-GFP antibody (green) and stained with α-Rab7 antibody (red) and Phalloidin (blue). (H,H’) Sagittal section showing total Hh signal (H) and Hh not colocalized with Rab7. White and yellow arrows indicate peripodial membrane and apical compartment, respectively. (I-K’) Same as (F-H’) for P compartment. (K) Graph showing the proportion of BAC encoded Hh:GFP signal that overlaps with Rab7 in apical/basolateral optical sections.

Figure Lengend Snippet: (A-E) Frontal views of unfixed wing discs, optical section close to the apical surface; left, anterior; right, posterior. (A,B) Wing discs expressing BAC-encoded GFP:Cherry:Smo without (A) and with ammonium chloride (B); GFP channel (green), RFP channel (red). (C) Wing disc expressing BAC-encoded GFP:Smo (green) and Rbcn3A RNAi (expressed during L3 at 29°C) in the dorsal region (below white dashed line) using ( ap-Gal4/tub-Gal80 ts ; GFP:Smo/Rbcn3A-RNAi ). (D,E) Unfixed wing discs expressing Cherry:Smo (red) and Rab5:YFP (green) (D) or Cherry:Smo (red) and Rab7:YFP (green). (F) Amount of Cherry:Smo/Rab7 double positive and Cherry:Smo /Rab5 double positive puncta.

Figure Lengend Snippet: Subcellular localization of the WT and D29N CrPV 2B proteins. Confocal microscopy images of Drosophila S2 cells transfected with plasmids encoding the indicated proteins. Cells were fixed 48 h after transfection and stained with ( A ) antibodies against the ER protein Calnexin 99A (Cnx99a) and the cis Golgi protein GM130, and ( B ) antibodies against the lysosome protein Rab7 (magenta). Nuclei were stained with DAPI. In the merged images in ( A ), eGFP is shown in green, Cnx99a in red, GM130 in magenta, and DAPI in blue.

Article Snippet: Calnexin 99A antibody (Developmental Studies Hybridoma Bank, Cnx99A 6-2-1; RRID:AB_2722011) was diluted 1:10, GM130 antibody (Abcam, ab30637) was diluted 1:250, Rab7 antibody (Developmental Studies Hybridoma Bank, RRID:AB_2722471) was diluted 1:10, and V5 antibody (Invitrogen, 46-0705) was diluted 1:200.
