A 2034 base pair fragment from the flanking non-coding or intronic region of SIFaR is fused upstream of a Drosophila synthetic core promoter (DSCP) followed by sequence encoding a GAL4 driver.
ScerGAL4VT007068 drives expression in some areas of the adult brain. In females expression in the posterior abdominal ganglion and the posterior superior medial protocerebrum is stronger than in males.
