RNA polymerase II is post-translationally modified on its C terminal domain and these modifications have been associated with different states of Pol II transcription. These modifications are now examined at a genome-wide level, and chemical inhibitors are used to argue that promoter-distal Ser7P is specifically placed anew by the Bur1 kinase.
