A 3740 base pair fragment from the flanking non-coding or intronic region of fkh is fused upstream of a Drosophila core synthetic promoter (DSCP) that is followed by sequence encoding a GAL4 driver.
ScerGAL4GMR17D02 drives expressing in the developing foregut and hindut from embryonic stages 9-12, in the complete intestinal tract from stages 13-17, in the Malpighian tubules from stages 13-16, and faintly in the developing CNS.
