A ninaE promoter fragment (from -833 to +67bp) drives expression of a mutated form of Gγ30A (carries the amino acid replacement C69G) tagged at the N-terminal end with Tag:MYC.
Flies expressing Gγ30AC69G.ninaE.T:Hsap\MYC show a decrease in light sensitivity (measured using electroretinogram analysis) compared to wild-type flies.
