A 3336 base pair fragment from the flanking non-coding or intronic region of Mef2 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.
