The R22H02 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 GMR20F03 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).
HsapRELAAD.R22H02 expression when combined with ScerGAL4DBD.R20F03 is stochastic in descending neuron of the gnathal ganglion DNg26.
Labelling of descending neuron of the gnathal ganglion DNg26 is stochastic.
