A 2556 base pair fragment from the flanking non-coding or intronic region of Kr is fused upstream of a Drosophila core synthetic promoter (DSCP) that is followed by sequence encoding a GAL4 driver.
ScerGAL4GMR87E08 drives expression in a subset of neurons in the adult mushroom body alpha-, beta- and gamma-lobes; expression is sparse in the gamma-lobes.
