UAS regulatory sequences drive expression of the TrpA1 TRPA1-B isoform. Since this line is derived from TrpA1UAS.(B).cKa, it also contains the H408R amino acid replacement present in that line.
Expression of TrpA1Scer\UAS.B.Kwon under the control of Scer\GAL4TrpA1.PR rescues the reduced avoidance to citronellal which is seen in TrpA11 flies in a direct airborne repellent test (DART) assay.
