The GMR48H08 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).

Optogenetic activation (using Cnoc\ChR1Cs.IVS.20xUAS.Venus with 590 nm (red) light) of neurons targeted by the split-GAL4 pair of Scer\GAL4DBD.R29G11 and Hsap\RELAAD.R48H08 in adults does not affect takeoff rates, compared to controls; spontaneous takeoffs are similar in duration to those of controls.
Silencing (using Hsap\KCNJ2IVS.10xUAS.EGFP) of neurons targeted by the split-GAL4 pair of Scer\GAL4DBD.R29G11 and Hsap\RELAAD.R48H08 in adults substantially and significantly reduces takeoff rates in response to looming stimuli, compared to controls; it also eliminates all aspects of giant fiber cell activity seen in controls in response to looming stimuli.
