Fig. 8. Dg is required to exclude NrxIV and Cont from the basal cell membrane. (A,B) NrxIV (red) is ectopically expressed in the basal membrane in Dg³²³ clones. (C,D) A similar phenotype is observed in trol clones. (E,F) In a Dg clone, Cont (red) accumulated together with NrxIV (green) at the basal membrane, whereas a change in Nrg (blue) distribution was not observed. Clones are marked by loss of GFP and indicated by broken lines. (B,D,F) Surface views of the FCE. (A'-F') Red channels; (E'',F'') green channels; (E''',F''') blue channels.
