title: Design and function of transcriptional switches in Drosophila.
abstract: Extensive genetic and biochemical analysis of Drosophila melanogaster has made this system an important model for characterization of transcriptional regulatory elements and factors. Given the striking conservation of transcriptional controls in metazoans, general principles derived from studies of Drosophila are expected to continue to illuminate transcriptional regulation in other systems, including vertebrates. With improvement in technologies for genetic manipulation of insects, research in Drosophila will also aid the design of systems for controlled expression of genes in other hosts. This review focuses on recent advances from Drosophila in analysis of the functional components of transcriptional switches, including basal promoters, enhancers, boundary elements, and maintenance elements.
