UAS regulatory sequences drive expression of an D724A mutant Ir8a with the endogenous signal sequence replaced with Tag:SS(hCALR) and fused to EGFP.
Neurons co-expressing Ir84aScer\UAS.cBa and Ir8aD724A.Scer\UAS.T:Hsap\CALR,T:Avic\GFP-EGFP under the control of Scer\GAL4Or22a.7.717 fail to respond to phenylacetaldehyde.
