A 3919 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.
In the wandering third instar larva ScerGAL4GMR77E08 drives expression in the optic lobe and in a small number of interneurons in the embryonic/larval central nervous system.
