A 1.5 kb DNA fragment carrying the -515 to +1035 region of Pdh (+1 is the transcription start site).
The rescue fragment is reported to extend from -515 to +1035 relative to the Pdh transcription start site. The start of Pdh-RA was used as the transcription start site for the mapping.
Pdh+t1.5 rescues Pdh1
The observed loss of deactivation afterpotential in electroretinogram recordings in older Pdh1 mutant flies is rescued by Pdh+t1.5.
