UASt regulatory sequences drive expression of a mutated form of dlg1 in which the PDZ2 and PDZ3 domains have been deleted. The protein is tagged at the C-terminal end with Tag:FLAG.
dlg1ΔPDZ2:3.UAS.Tag:FLAG/Scer\GAL469B partially rescues dlg114
Scer\GAL469B-mediated expression rescues the septate junction formation in dlg114 mutants but the imaginal discs are still slightly overgrown.
