A 3578 base pair fragment from the flanking non-coding or intronic region of sNPF-R is fused upstream of a Drosophila core synthetic promoter (DSCP) that is followed by sequence encoding a GAL4 driver.
In the wandering third instar larva ScerGAL4GMR64F07 drives expression in two pairs of mushroom body extrinsic neurons, in the adult labeling is detected in only one pair.
