Co-transcriptional imprinting mRNAs with decay mediators. Model proposes that the Rpb4/7 module of RNAPII associates with mRNAs co-transcriptionally, remains associated with mRNAs as they are exported from the nucleus, and their abundance regulates subsequent decay events. Question mark represents the controversial role of Rpb4/7 in mRNA decay and synthesis. Also shown is the CCR/NOT mRNA deadenylase complex that may also coordinate both processes.
