Fig. 6. An Akap200 mutation dominantly suppresses the Src64B ring canal size phenotype. (A-D) Confocal projection of egg chambers stained with phosphotyrosine antibodies. (A) Wild-type stage-ten egg chamber. (B) Src64B^PI/Src64B^PI stage-ten egg chamber. Note small ring canals and misshapen ring canal remnant in the fused, binucleate nurse cell (arrow). (C) Akap200^k07118/+; Src64B^PI/Src64B^PI stage-ten egg chamber. The ring canals are near wild-type-sized. (D) Akap200^k07118/Akap200^k07118; Src64B^PI/+ stage-ten egg chamber. Ring canals are near normal sized; a ring canal remnant is indicated with an arrowhead. (E) Src64B^PI/Src64B^PI early stage-ten egg chamber stained with Akap200 antiserum. Except for the small ring canals, Akap200 localization in these mutants appears normal.
