A 3010 base pair fragment from the flanking non-coding or intronic region of Pvf3 is fused upstream of a Drosophila core synthetic promoter (DSCP) that is followed by sequence encoding a GAL4 driver.
ScerGAL4GMR77E12 drives expression in mushroom body extrinsic neurons that innervate mushroom body gamma lobe slice 5, mushroom body beta lobe slices 1 and 2, and mushroom body beta' lobe slice 2.
