A 988 base pair fragment from the flanking non-coding or intronic region of CG9657 is fused upstream of a Drosophila core synthetic promoter (DSCP) that is followed by sequence encoding a GAL4 driver.
ScerGAL4GMR56C01 drives expression in adult central brain ensheathing glia; labeled glia are located in sleep centers, in high numbers near the mushroom bodies and fan-shaped bodies, and in low numbers near the ellisoid body.
