The VT019911 enhancer fragment followed by the Drosophila synthetic core promoter (DSCP) is fused upstream of the p65(AD)::Zip+ hemidriver (component of a 'split driver' system, contains the p65 activation domain).
Comment: when combined with P{VT010054-GAL4.DBD} (combination referred to as 'hg1-SG2')

Silencing (using Ctet\TeTxLCTNT.UAS) of neurons targeted by the split-GAL4 pair of Scer\GAL4DBD.VT010054 and Hsap\RELAAD.VT019911 in adult males significantly alters some parameters of pulse song and sine song, compared to controls; there is no significant effect on the number of males that sing, or take off and forced flight ability, but there is a significant reduction in copulation success, compared to controls.
