The GMR44B10 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).
Comment: when combined with P{R30G06-p65.AD} (combination referred to as 'SS0020')
Optogenetic activation (using Cnoc\ChR1Cs.IVS.20xUAS.Venus with 617 nm (red) light) of neurons targeted by the split-GAL4 pair of Scer\GAL4DBD.R44B10 and Hsap\RELAAD.R30G06 in adults does not affect preference for being in the region of activation (illuminated region), compared to controls.
