Direct coupling of the human nuclear exosome adaptors NEXT and PAXT with transcription termination and processing machineries Abstract. In human cells, the Nuclear EXosome Targeting (NEXT) and Poly(A) tail eXosome Targeting (PAXT) adaptors direct the nuclear exosome to degrade pre

Pleased to be a small part of this collaboration with the @labconti.bsky.social now published at @narjournal.bsky.social.
Here we combine structure prediction, biochem, cryo-EM, and IP-based approaches to explore connections between RNA quality control to transcription termination complexes.

Messenger RNA is made in the nucleus before it is exported to the cytoplasm for translation. But how are only correctly made mRNAs chosen and remodeled in the nucleus for export?
Our new paper investigates the nuclear events leading to human mRNA export. www.nature.com/articles/s41.... (1/4)

RX Bandits - ...and the Battle Begun

Thrilled to share that I’ll be joining @imbmainz.bsky.social in February 2026 to start my own group!
We will explore new mechanisms in eukaryotic gene expression, leveraging ‘evolutionary play’ to uncover how regulation, repurposing, and hijacking shape RNA biology.
PhD positions available!

Molecular basis of polyadenylated RNA fate determination in the nucleus Eukaryotic genomes generate a plethora of polyadenylated (pA+) RNAs, that are packaged into ribonucleoprotein particles (RNPs). To ensure faithful gene expression, functional pA+ RNPs, including prote...

How do cells sort which RNAs to keep or destroy? New preprint from THJ, Brenneke and Plaschka labs shows that export and decay machineries (TREX2/PAXT) both recognise UAP56-bound RNAs. Whether they’re exported or degraded depends on where in the nucleus this happens.

We put together a spotlight for @cp-cellchembiol.bsky.social highlighting the recent work from @baluapuri.bsky.social and @adelmanlab.bsky.social published in @cp-cell.bsky.social.

Here they show how a breakdown in nuclear RNA regulation sends ripples of stress throughout the cell.

International recognition for Aarhus researchers: RNA science takes off RNA research in Aarhus is taking a significant leap forward. Two researchers from the same department and research environment have both just been awarded one of Europe’s most prestigious research gra...

Restrictor slows early transcription elongation to render RNA polymerase II susceptible to termination at non-coding RNA loci www.biorxiv.org/content/10.1101/2025.01....

Is there a common contaminant database for proximity labelling-MS data? I see that the CRAPome has a section for proximity-dependent biotinylation but it is limited to human cells.
I keep seeing the same nonsense proteins enriched in mTurbo-experiments and would love to know if this is common crap.

40 years ago all of Genbank was published in print form by NAR. The same format today would require over 4 light seconds of shelf space. To a year of progress in 2025.

Cell lines are frozen, chrome tabs, spreadsheets and documents have been closed. All done for this year ✌️
Back in Derbyshire and busy making sausage rolls.
It's been a productive year, but i'm in dire need of a break.

RNA 3′end tailing safeguards cells against products of pervasive transcription termination - Nature Communications Pervasive transcription generates numerous unadenylated RNAs, usually degraded by the NEXT/nuclear exosome pathway. Here, the authors show that, upon NEXT inactivation, these RNAs are removed by compe...

doi.org/10.1038/s414...

📢 Latest publication from the lab! We explore how cells manage the excess pA− RNAs generated by pervasive transcription. While the NEXT complex usually takes charge, in its absence, a network of tailing enzymes, export factors, and exonucleases steps in to modify and degrade these RNAs.
