A 877 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.
ScerGAL4GMR93H01 drives expression in the lining of the embryonic esophagus, in the visual primordium, in the embryonic SNS, and in receptor cells at the anterior of the embryo.
