The messenger RNA processing reactions of capping, splicing, and polyadenylation occur cotranscriptionally. They not only influence one another's efficiency and specificity, but are also coordinated by transcription. The phosphorylated CTD of RNA polymerase II provides key molecular contacts with these mRNA processing reactions throughout transcriptional(More)
Reconstruction of a gene with its introns removed results in reduced levels of cytoplasmic mRNA. This is partly explained by introns promoting the export of mRNA through coupling splicing to nuclear export processes. However, we show here that splicing signals can have a direct role in enhancing gene transcription. Removal of promoter proximal splice(More)
