UAS regulatory sequences drive expression of the "TRPA1(A)" isoform. Note that the isoform referred to as TRPA1(A) in FBrf0222493 is similar to that called "TRPA1-D" in FBrf0217493, except that "TRPA1(A)" has an additional N-terminal amino acids.
Expression of TrpA1Scer\UAS.(A).10b under the control of Scer\GAL4TrpA1.C-D is unable to rescue the uracil-dependent defecation defect, but is able to rescue the N-methylmaleimide-dependent defecation defect of TrpA1ins mutants.
Expression of TrpA1Scer\UAS.(A).cKa under the control of Scer\GAL4Gr66a.PD restores an electrophysiological spiking response to N-methylmaleimide in berberine-sensitive i-type taste bristles in the labellum in TrpA1ins flies. Sensitivity to warming is not restored.
