The VT059793 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{R58F03-GAL4.DBD} (combination referred to as 'SS01970')
Acute, high intensity optogenetic activation (using Cnoc\ChR1Cs.IVS.20xUAS.Venus with 617 nm (red) light) of neurons targeted by the split-GAL4 pair of Scer\GAL4DBD.R58F03 and Hsap\RELAAD.VT059793 in larvae induces contraction of transverse muscle LT2, but not longitudinal muscle LO1, compared to baseline; chronic, low-level stimulation causes transverse muscle LT2 to contract earlier than normal in the locomotor cycle, reducing the phase offset between LT2 and LO1 contractions, compared to baseline.
