A 2660 base pair fragment from the flanking non-coding or intronic region of Gsc is fused upstream of a Drosophila core synthetic promoter (DSCP) that is followed by sequence encoding a GAL4 driver.
ScerGAL4GMR84B07 drives expression in the exterior brain lobes in the developing CNS; faint expression is driven at the CNS midline at late embryonic stages.
