A 3107 base pair fragment from the flanking non-coding or intronic region of AlstR is fused upstream of a Drosophila core synthetic promoter (DSCP) that is followed by sequence encoding a GAL4 driver.
ScerGAL4GMR22C12 drives expression in mushroom body extrinsic neurons that innervate mushroom body gamma lobe slice 2, mushroom body beta lobe slice 2, mushroom body beta' lobe slice 2 and mushroom body alpha' lobe slice 1.
