And finally:
The effect of SETD2 on transcription is indirect - it likely acts upstream, modulating a plethora of transcription factors. (5/5)

SETD2’s control of readthrough is independent of alternative polyadenylation. It highlights the importance of distinguishing these two processes: 3’ end processing & termination are not the same❗ (4/5)
mgkopczynska.bsky.social
In cells that don’t have SETD2 or it’s catalytically inactive, readthrough happens because:
1️⃣ TSS initiation is maintained,
2️⃣ 3’ end cleavage is impaired,
3️⃣ cryptic intragenic transcription gets triggered, especially close to the gene ends. (3/5)
mgkopczynska.bsky.social
We show that SETD2 activity has pleiotropic effects on protein-coding genes:
🟢 promotes proper transcription initiation for most of them (class I),
🛑 stimulates termination in ~20% - prevents transcriptional readthrough (class II). (2/5)

🚨 New preprint from our labs (STOP lab @stoplab.bsky.social & Nojima lab @pol2rna.bsky.social @pyrolyn.bsky.social)! We've been digging into how chromatin remodeler SETD2 controls the start and end of transcription 👇 www.biorxiv.org/cgi/content/... (1/5)

I don't exclude this option :))

Honored to receive an award from @polskaakademianauk.bsky.social in Poznań for the best 2024 publication led by a PhD student. Our study published in @narjournal.bsky.social highlights a key marker defining gene ends — helping improve genome annotations.

Happy to see the first first-author paper from my PhD out! Huge thanks to all co-authors and of course to my brilliant supervisor @stoplab.bsky.social 🙏

Usage of T4ph as a termination marker could benefit more comprehensive genome annotations and help with annotating disease-associated mutations outside of coding regions.
mgkopczynska.bsky.social
We summarize the findings from literature regarding T4ph and its role in transcription termination. We also provide new analyses that confirm association of T4ph with regions where transcription stops - both at the gene end and prematurely, within the gene body.

Do you know where transcription of a gene actually stops? Hint: it is not the annotated gene end.
In our new paper in Nucleic Acids Research we argue that phosphorylation on threonine 4 of RNA Pol II CTD is a marker of transcription termination in animals... 🧵
