A 2068 base pair fragment from the flanking non-coding or intronic region of Ir64a is fused upstream of a Drosophila synthetic core promoter (DSCP) followed by sequence encoding a GAL4 driver.
ScerGAL4VT026000 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 alpha lobe slice 2 and mushroom body alpha' lobe slice 2.
