The GMR11B11 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).
The GMR34C03 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).
In a split-GAL4 system, HsapRELAAD.R11B11 drives expression in antennal grooming brain interneuron 1 when combined with ScerGAL4DBD.R34C03, and in antennal grooming brain interneuron 1 and the adult central complex when combined with ScerGAL4DBD.R71D01. Projections from antennal grooming brain interneuron 1 were seen in close proximity to EcollexAGMR18C11 expressing antennal grooming descending neuron 1-3, to EcollexAGMR27H08 expressing zone C/E Johnston organ neurons and projections from four EcollexAGMR26B12 expressing antennal grooming brain interneuron 2. Positive GRASP (GFP reconstitution across synaptic partners) signals were seen between C/E Johnston organ neurons and antennal grooming brain interneuron 1 using these drivers.
