7.0kb SalI fragment that includes the rdgC transcription unit.
A 7.0kb SalI rescue fragment is reported; The 3' SalI site is absent from the reference sequence; therefore, the annotated 3' end of the rescue fragment is approximate; position of restriction fragment on reference sequence inferred by FlyBase curator.
When the retina of mutant animals are exposed to 0.5 sec pulses of orange light and the photoresponse measured, a corneal negative deflection is seen in the Electroretinogram (ERG). Upon termination of the light response there is a rapid return to the baseline. These flies also exhibit a normal, prolonged depolarisation afterpotential (PDA).
rdgC+t7.0 is capable of supplying wild-type rdgC function in rdgC mutant flies.
