A 2863 base pair fragment from the flanking non-coding or intronic region of CcapR is fused upstream of a Drosophila core synthetic promoter (DSCP) that is followed by sequence encoding a GAL4 driver.
ScerGAL4GMR64B05 drives expression in one type Ib and one type II motor neuron per hemineuromere that innervate several ventral and lateral muscles.
