In the eye-antennal disc, ScerGAL4cb41 drives expression in the developing eye, in most of the presumptive antenna, and in the presumptive ocellus.
ScerGAL4cb41 drives expression in the embryonic PNS and antenno-maxillary complex, and in the larval CNS and all imaginal discs. During oogenesis, ScerGAL4cb41 drives expression in a few scattered follicle cells at stages S1-14, and in centripetally migrating follicle cells at stages S10-14.
