Abstract
Transcriptional repressors can be characterized by their range of acti on on promoters and enhancers. Short-range repressors interact over di stances of 50-150 bp to inhibit, or quench, either upstream activators or the basal transcription complex. In contrast, long-range repressor s act over several kilobases to silence basal promoters. We describe r ecent progress in characterizing the functional properties of one such long-range element in the Drosophila embryo and discuss the contrasti ng types of gene regulation that are made possible by short- and long- range repressors.
