A 3852 base pair fragment from the flanking non-coding or intronic region of dnc is fused upstream of a Drosophila core synthetic promoter (DSCP) followed by sequence encoding a lexA::p65 driver. The driver sequence has been optimized for Drosophila codon usage. An Hsp70 transcriptional terminator is present.
Expression driven by EcollexAGMR13F02 overlaps with that driven by the split-GAL4 combinations HsapRELAAD.R52G04 and ScerGAL4DBD.R49F03 that drive expression in the medulla columnar neuron VPN-MB2, and ScerGAL4DBD.R10E05 and HsapRELAAD.R28F07 that drive expression in medulla columnar neuron MC63.
