A 1866 base pair fragment from the flanking non-coding or intronic region of Dh31 is fused upstream of a Drosophila core synthetic promoter (DSCP) that is followed by sequence encoding a GAL4 driver.
Activation of Scer\GAL4GMR20A02-expressing neurons (using heat activation of a TrpA1 construct) significantly suppresses both daytime and nighttime sleep, indicating that these neurons are wake promoting.
