A candidate cis-regulatory fragment (genomic DNA) is fused upstream of a Drosophila synthetic core promoter (DSCP) followed by sequence encoding a GAL4 driver.
ScerGAL4VT10277 labels antennal mechanosensory and motor center B1b (AMMC1-B1b) projection neurons that respond maximally to auditory stimuli of 100Hz and 300Hz.
