A 2784 base pair fragment from the flanking non-coding or intronic region of 5-HT1A is fused upstream of a Drosophila core synthetic promoter (DSCP) that is followed by sequence encoding a GAL4 driver.
ScerGAL4GMR53C10 drives expression in mushroom body extrinsic neurons that innervate mushroom body gamma lobe slices 1, 2 and 4, mushroom body beta lobe slice 1, mushroom body beta' lobe slice 2 and mushroom body alpha lobe slices 1, 2 and 3.
