Identification of sequence-specific promoters driving polycistronic transcription initiation by RNA polymerase II in trypanosomes

Abstract excerpt

Protein-coding genes in trypanosomes occur in polycistronic transcription units (PTUs). How RNA polymerase II (Pol II) initiates transcription of PTUs has not been resolved; the current model favors chromatin modifications inducing transcription rather than sequence-specific promoters. Here, we uncover core promoters by functional characterization of Pol II peaks identified by chromatin immunoprecipitation...
