The R21D02 enhancer fragment is fused upstream of the Drosophila synthetic core promoter (DSCP) followed by the p65(AD)::Zip+ hemidriver (component of a 'split driver' system, contains the p65 activation domain). A Hsp70 transcriptional terminator is present.

Inhibition (using Hsap\KCNJ25XUAS.EGFP) of neurons targeted by the split-GAL4 pair of Scer\GAL4DBD.R55D08 and Hsap\RELAAD.R21D02 in third instar larvae significantly impairs short-term associative appetitive olfactory memory following training with fructose, with no effect on innate odor (n-amylacetate) or fructose preference, compared to controls.
Optogenetic activation (using Crei\ChR2XXL.UAS with 470 nm (blue) light) of neurons targeted by the split-GAL4 pair of Scer\GAL4DBD.R55D08 and Hsap\RELAAD.R21D02 in third instar larvae during training or testing significantly impairs short-term appetitive olfactory memory following training with fructose, compared to controls; activation in combination with a paired odor, or fructose exposure, does not significantly affect subsequent preference for these stimuli, compared to controls.
Blocking protein synthesis (using Rcom\RA[cs2.UAS] at 30[o]C) for the full 24 h between spaced training and testing in neurons targeted by the split-GAL4 pair of Scer\GAL4DBD.R22C12 and Hsap\RELAAD.R21D02, does not significantly affect aversive olfactory long term memory in adults, compared to wild-type controls.
Thermogenetic activation (using TrpA1UAS.(B).cKa at 28.5[o]C) of neurons targeted by the split-GAL4 pairs of Scer\GAL4DBD.R12C11 and Hsap\RELAAD.R21D02, or Scer\GAL4DBD.R22C12 and Hsap\RELAAD.R21D02, in adult males does not significantly affect the amount of sleep, compared to controls; activation does not significantly affect locomotor activity of awake adult males, compared to controls.
Optogenetic activation (using Cnoc\ChR1::Csub\ChRCsChrimson.IVS.20xUAS.Venus with 617 nm (red) light) of neurons targeted by the split-GAL4 pair of Scer\GAL4DBD.R22C12 and Hsap\RELAAD.R21D02 in adult females in an area of an arena does not significantly affect time spent in that area, compared to controls.
Inhibition (using shits1.IVS.p10.20xUAS at 31-33[o]C) of neurons targeted by the split-GAL4 pair of Scer\GAL4DBD.R22C12 and Hsap\RELAAD.R21D02 in adults during training, consolidation and testing does not substantially reduce aversive or attractive 2 h associative olfactory memory, or appetitive 1 min associative visual memory, compared to controls; inhibition during testing alone does not significantly reduce aversive 24 h associative olfactory memory, compared to controls, and inhibition only during training and testing does not significantly reduce 24 h appetitive, or 30 min aversive, associative olfactory memory towards ethanol, compared to controls.
Thermogenetic activation (using TrpA1UAS.(B).cKa at 28.5[o]C) of neurons targeted by the split-GAL4 pair of Scer\GAL4DBD.R22C12 and Hsap\RELAAD.R21D02 in adults does not significantly affect sleep, compared to controls, and there is no effect on social or locomotor behaviors.
