The GMR76F12 enhancer fragment followed by the Drosophila synthetic core promoter (DSCP) is fused upstream of the GAL4(DBD)::Zip- hemidriver (component of the 'Split GAL4' system, contains the GAL4 DNA-binding domain).
Thermogenetic activation (using TrpA1Scer\UAS.(B).cKa at 30-31[o]C) of neurons targeted by the split-GAL4 pair of Scer\GAL4DBD.R76F12 and Hsap\RELAAD.R70H02 results in a significant increase of antennal grooming behavior compared to control flies; there is a further significant increase in antennal grooming behavior following antennal amputation.
