A 2759 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.
ScerGAL4GMR16E04 drives expression in the lining of the embryonic and larval hindgut; faint expression is also observed in the developing midgut.
