A 600bp enhancer region from the RluA-1 promoter is fused upstream the the Drosophila Synthetic Core Promoter (DSCP) promoter and coding sequence for the GAL4 driver.
ScerGAL4RluA-1.Rluv3 drives expression solely in DA neurons at larval stages; expression levels are enriched in larval multidendritic class I neurons, with expression observed very early in postmitotic class I neurons.
