UAS regulatory sequences drive expression of an R317A mutant Ir84a with the endogenous signal sequence replaced with Tag:SS(hCALR) and fused to EGFP.
Neurons co-expressing Ir84aR317A.Scer\UAS.T:Hsap\CALR,T:Avic\GFP-EGFP and Ir8aScer\UAS.cAa under the control of Scer\GAL4Or22a.7.717 fail to respond to phenylacetaldehyde.
