The R52G04 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 GMR49F03 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.R52G04 drives expression in 1-3 medulla columnar neuron VPN-MB2 as well as mushroom body output neuron 7 when combined with ScerGAL4DBD.R49F03 and in mushroom body output neuron 7 when combined with ScerGAL4DBD.R17C11. Expression overlaps with that driven by EcollexAGMR13F02 in the Kenyon cells. Positive GRASP (GFP reconstitution across synaptic partners) signals were seen between medulla columnar neuron VPN-MB2 and gamma dorsal Kenyon cells using these split-GAL4 drivers and AvicGFPspGFP11.Mef2.mb247.T:HsapCD4.
