Imprecise excision of the progenitor insertion, resulting in a deletion of 1631bp which removes part of CG4476 (173 amino acids which includes all of the first three transmembrane domains and a portion of the second extracellular loop are predicted to be deleted).
An 1631bp deletion resulting from the imprecise excsion of P{XP}CG4476d11470, which extends from the insertion site into CG4476 and removes the first 173 amino acids.
Mutants have no evident morphological eye defects.
Electroretinograms of mutant flies show normal retinal depolarization and on/off-transients when exposed to a brief pulse of light.
Mutant flies are not responsive to light in a fast phototaxis assay (their behaviour is identical in the light and in the dark).
