title: Running with RNA polymerase: eukaryotic transcript elongation.
abstract: Long recognized as a target of regulation in prokaryotes, transcript elongation has recently become the focus of many investigators interested in eukaryotic gene expression. The growth of this area has been fueled by the availability of new methods and molecular structures, expanding sequence databases and an appreciation for the exquisite coordination required among different processes in the nucleus. Our article collates new information on regulatory accessory factors, as well as their ultimate target, RNA polymerase, in the nucleus of eukaryotic cells. How this regulation influences the biology of the organism is quite profound, and from single cell to multicellular eukaryotes significant similarities exist in the molecular responses to extracellular signals during transcript elongation. The most advanced genetic knowledge in this area comes from Saccharomyces cerevisiae, but the biochemistry and cell biology results from other organisms are also highlighted.
