The GMR58F03 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).

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.
