A 3567 base pair fragment from the flanking non-coding or intronic region of Hr38 is fused upstream of a Drosophila core synthetic promoter (DSCP) that is followed by sequence encoding a GAL4 driver.
ScerGAL4GMR35F03 drives expression in three type Ib and type II motor neurons per hemineuromere that innervate ventral, lateral, and dorsal muscles.
