The CarT promoter region (from -2579 to +11bp relative to the transcription start site) drives expression of the complete CarT coding region (derived from the GH05908 cDNA) tagged with mCherry.
CarTmCherry rescues CarT1
CarTT:Disc\RFP-mCherry rescues on and off transients in ERGs and restores phototaxis similar to wild type in CarT1/CarT1 flies.
