Genome expression involves the synthesis of messenger RNA (mRNA), a short lived molecule whose translation directs the synthesis of cellular proteins and that is subject to degradation after the translation process. Up to the date, mRNA synthesis and degradation has been considered as a linear phenomenon in which the above steps occur...

Co-transcriptional imprinting of mRNA by Rpb4 and Rpb7 subunits of RNA polymerase II (RNAPII) and by the Ccr4–Not complex conditions its posttranscriptional fate. In turn, mRNA degradation factors like Xrn1 are able to influence RNAPII-dependent transcription, making a feedback loop that contributes to mRNA homeostasis. In this work, we have...
