UAS regulatory sequences drive expression of rdgB in which the core residues of the FFAT motif have been mutated from EFFDCLD to EAAACLD.
Scer\GAL4ninaE.PU/rdgBFFD-AAA.UAS fails to rescue rdgB9
The expression of rdgBFFD-AAA.Scer\UAS under the control of Scer\GAL4ninaE.PU fails to rescue the severely decreased electroretinogram peak amplitude observed in rdgB9 homozygotes.
