A 3650 base pair fragment from the flanking non-coding or intronic region of fru is fused upstream of a Drosophila core synthetic promoter (DSCP) that is followed by sequence encoding a GAL4 driver.
ScerGAL4GMR22G11 drives expression in lineage 1 neurons.
ScerGAL4GMR22G11 is expressed in 19-23 adult fruitless pMP-e (male) neurons and over 500 other neurons in the male brain.
