A 3733 base pair fragment from the flanking non-coding or intronic region of Dl is fused upstream of a Drosophila core synthetic promoter (DSCP) that is followed by sequence encoding a GAL4 driver.
ScerGAL4GMR24H06 drives expression in intestinal stem cells, and in the copper cell region of the midgut (adult midgut regions R3a and R3b).
