A 2356 base pair fragment from the flanking non-coding or intronic region of dimm is fused upstream of a Drosophila core synthetic promoter (DSCP) that is followed by sequence encoding a GAL4 driver.
ScerGAL4GMR10D10 drives expression in distal satellite cells that encase the cell bodies of lamina monopolar neurons L1-L4 as well as in marginal glial cells.
