A 3943 base pair fragment from the flanking non-coding or intronic region of RunxB is fused upstream of a Drosophila core synthetic promoter (DSCP) that is followed by sequence encoding a GAL4 driver.
ScerGAL4GMR84E08 drives expression in a subset of cold and hot activated thermosensitive transverse antennal lobe tract projection neuron terminating in the lateral horn and the posterior lateral protocerebrum.
