A 514 base pair fragment from the flanking non-coding or intronic region of mun is fused upstream of a Drosophila core synthetic promoter (DSCP) that is followed by sequence encoding a GAL4 driver.
ScerGAL4GMR93G11 drives embryonic expression at the anterior tip of the esophagus, in the esophageal ganglion, in the brain lobes including in a large posterior cluster, and in some larval anterior midgut cells.
