摘要: Over the past few years, advances in biochemical and genetic studies of structure function Mediator complex have shed new light on its subunit architecture mechanism action transcription by RNA polymerase II (pol II). The development improved methods for reconstitution recombinant subassemblies is enabling more in-depth analyses basic features mechanisms which interacts with controls activity pol general initiation factors. discovery characterization multiple, functionally distinct forms characterized presence or absence Cdk8 kinase module led to insights into how functions both Pol activation repression. Finally, progress transcriptional domains (ADs) DNA binding factors target brought unexpected complexities way participates signal transduction.
