Cytoplasmic mRNA turnover in fission yeast


Gene expression depends on RNA molecules. RNA stability and functionality can be controlled by post-transcriptional modifications. One of such modifications is uridylation – the addition of one to several uridine residues to the 3′ end of an RNA molecule. Uridylation has been detected in both non-coding and messenger RNA (mRNA) of most eukaryotic organisms. Uridylation usually leads to destabilization and degradation of molecules. It is a pervasive modification of most cellular mRNAs, however, its exact contribution to bulk mRNA decay is still unclear.

In my laboratory, we use fission yeast (Schizosaccharomyces pombe) as a model to study the role of uridylation in bulk mRNA turnover.


Information for attendees

The Seminars are held in English, on-line using the ZOOM platform. The Seminars are open and all are welcome to attend. Duration: up to 40 minutes of presentation and 20 minutes of discussion.

When joining the meeting, please turn off the microphone and camera and use your full name as the participant’s identifier. After the presentation, it will be possible to ask questions via text communication (“chat” option) or audio communication (microphone).
