Drives expression in sensory neurons at larval, pupal, and adult stages.
ScerGAL45-40 expresses in mechanosensory neurons associated with the halteres and some bristles.
ScerGAL45-40 drives expression in the PNS neurons, including multidendritic neurons (bipolar and class I-IV), external sensory organs and chordotonal organs. Expression in the CNS is restricted to weak labelling in a small number of cells.
