A 3508 base pair fragment from the flanking non-coding or intronic region of dsx is fused upstream of a Drosophila core synthetic promoter (DSCP) that is followed by sequence encoding a GAL4 driver.
Thermogenetic activation (using TrpA1UAS.(B).cKa at 27[o]C) of Scer\GAL4GMR41D01 cells in adult virgin females significantly reduces copulation within 10 min of introduction to a male, compared to baseline, unlike controls.
