UASt regulatory sequences drive expression of the predicted full length Ir92a coding region (nucleotides 16164695-16169624 of AE014297).
abnormal smell perception, with Scer\GAL4Ir76a.PB
coeloconic sensillum of antennal segment 3, with Scer\GAL4Ir76a.PB
Expression of Ir92aScer\UAS.cBa under the control of Scer\GAL4Ir76a.PB results in the ac4 sensilla becoming sensitive to stimulation by ammonia in an olfactory assay. 1,4-diaminobutane does not activate the ac4 sensilla expressing Ir92aScer\UAS.cBa under the control of Scer\GAL4Ir76a.PB.
