Spatial targeting of transgene expression in Drosophila. GAL4/UAS system. Driver lines expressing the transcriptional activator GAL4 in a tissue-specific fashion are crossed to UAS-lines with genomic inserts of a target gene fused to five GAL4-binding sites arrayed in tandem (5 × UAS) (shown here as UAS-Aβ42).
