A 3308 base pair fragment from the flanking non-coding or intronic region of sNPF 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.
EcollexAGMR20F11 drives expression in a pair of glucose-sensing dorsolateral neurons that also express Crz and sNPF.
