The VT022025 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{VT019911-GAL4.DBD} (combination referred to as 'hg2-SG2')

Silencing (using Ctet\TeTxLCTNT.UAS) of neurons targeted by the split-GAL4 pair of Scer\GAL4DBD.VT029310 and Hsap\RELAAD.VT022025 in adult males results in a significant reduction in the number of males that sing courtship song to females, with significant alterations in some parameters of pulse song, but not sine song, compared to controls; there is no significant effect on wing extension toward females or copulation success; take off and forced flight ability are significantly impaired, compared to controls.
