A 3271 base pair fragment from the flanking non-coding or intronic region of sc is fused upstream of a Drosophila core synthetic promoter (DSCP) that is followed by sequence encoding a GAL4 driver.
ScerGAL4GMR15A01 is expressed in 7-9 fru positive adult fruitless pMP-e (male) neurons and 80-100 other neurons in the male brain.
