The R64G09 enhancer fragment is fused upstream of the Drosophila synthetic core promoter (DSCP) followed by the p65(AD)::Zip+ hemidriver (component of a 'split driver' system, contains the p65 activation domain). A Hsp70 transcriptional terminator is present.
The R37H04 enhancer fragment is fused upstream of the Drosophila synthetic core promoter (DSCP) followed by the GAL4(DBD)::Zip- hemidriver (component of the 'Split GAL4' system, contains the GAL4 DNA-binding domain). A Hsp70 transcriptional terminator is present.
In a split-GAL4 system, HsapRELAAD.R64G09 drives expression in lobula complex columnar neuron LPLC1 and a subset of neurons in the thoracico-abdominal ganglion when combined with ScerGAL4DBD.R37H04.
