A 2300 base pair fragment from the flanking non-coding or intronic region of cac is fused upstream of a Drosophila core synthetic promoter (DSCP) that is followed by sequence encoding a GAL4 driver.
ScerGAL4GMR55C02 drives expression mainly in antennal mechanosensory and motor center local AMMC anterolateral neuron, but also drives expression in 3 cells innervating the thoracico-abdominal ganglion.
