A 1373 base pair fragment from the flanking non-coding or intronic region of Takr99D is fused upstream of a Drosophila core synthetic promoter (DSCP) that is followed by sequence encoding a GAL4 driver.
ScerGAL4GMR65H09 drives expression in one neuromodulatory motor neuron (type II or type III, but not type I) per hemineuromere that innervates ventral, lateral, and dorsal muscles. This motor neuron is included in the abdominal transverse nerve.
