The GMR26D04 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{R48H02-GAL4.DBD} (combination referred to as 'SS02064')
Optogenetic activation (using Cnoc\ChR1Cs.IVS.20xUAS.Venus with 660 nm (red) light) of neurons targeted by the split-GAL4 pair of Scer\GAL4DBD.R48H02 and Hsap\RELAAD.R26D04 in larvae induces musculature contractions that result in tail flicking.
Inhibition (using shi1.UAS at 31[o]C) of neurons targeted by the split-GAL4 pair of Scer\GAL4DBD.R48H02 and Hsap\RELAAD.R26D04 in larvae significantly reduces the probability of backwards motion in response to a head touch, with no effect on the peristaltic motion itself, compared to controls.
