UAS regulatory sequences drive expression of an R481E mutant Ir8a with the endogenous signal sequence replaced with Tag:SS(hCALR) and fused to EGFP.
Neurons co-expressing Ir84aScer\UAS.cBa and Ir8aR481E.Scer\UAS.T:Hsap\CALR,T:Avic\GFP-EGFP under the control of Scer\GAL4Or22a.7.717 show a moderate but significant reduction in phenylacetaldehyde responses.
