The VT029310 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).

Silencing (using Ctet\TeTxLCTNT.UAS) of neurons targeted by the split-GAL4 pair of Scer\GAL4DBD.VT029310 and Hsap\RELAAD.VT022025, or the split-GAL4 pair of Scer\GAL4DBD.VT029310 and Hsap\RELAAD.VT040232, 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; take off and forced flight ability are also significantly impaired; in the case of Scer\GAL4DBD.VT029310 and Hsap\RELAAD.VT022025 there is no effect on wing extension toward females; in the case of Scer\GAL4DBD.VT029310 and Hsap\RELAAD.VT040232, but not Scer\GAL4DBD.VT029310 and Hsap\RELAAD.VT022025, most individuals have altered wing posture (drooping) and a significant reduction in copulation success, compared to controls.
Optogenetic activation (using Cnoc\ChR1Cs.IVS.20xUAS.Venus with 590 nm (yellow) light) of neurons targeted by the split-GAL4 pair of Scer\GAL4DBD.VT029310 and Hsap\RELAAD.VT040232 in adult males results in wing lifting.
