GMR regulatory sequences drive expression of the complete rl coding sequence, followed by amino acids 2-147 of Scer\GAL4 (includes the DNA-binding domain), followed by residues 413-490 of Hsim\VP16 (activation domain), followed by a Tag:HSV-1-gD epitope tag.
ommatidium, with rlSem
rlSem/+ flies have a rough eye phenotype, which is enhanced if the flies also express rlGMR.T:Scer\GAL4,T:Hsim\VP16,T:Hsim\gD.
