super cool

Raymond stands at the centre of the picture next to the entrance to the seminar room. He is surrounded by five family members including his wife.

Yesterday we came together to honour Professor Raymond Dwek through the naming of the Raymond Dwek Seminar Room. Raymond's family (pictured) joined the celebration and Raymond was visibly touched, saying: "Thank you for this amazing gesture. I'm humbled by it, but I will treasure it."

RNA-binding proteins and ribonucleoproteins as determinants of immunity - Nature Reviews Immunology RNA-binding proteins (RBPs) considerably expand the information content of the genome and can determine the lifespan, localization and function of RNA, thereby controlling when, where and how much pro...

gives our perspective on this growing area of research. Special thanks to the editor Alexandra, for streamlining the manuscript.

an interesting work on how RNA regulatory elements control immune systems.

differential contribution of H3K9 methyltransferases to boundaries at satellites

A new and fascinating story from @bencarty.bsky.social and the group, with crucial help from the teams of @naltemose.bsky.social, Simona Giunta, and @dfachinetti.bsky.social. Many thanks to all for a fantastic collaboration.

Sequential verification of transcription by Integrator and Restrictor Estell and Łazowski et al. show that Integrator and Restrictor form distinct pathways for early attenuation of RNA polymerase II: Integrator acts at the promoter-proximal pause site, whereas Restricto...

I’m a fair-weather poster on here to say the least. However, I'm pleased to present our latest paper. A great effort from all authors and an interesting insight into transcriptional regulation (we think!).

Reporter CRISPR screens decipher cis-regulatory and trans-regulatory principles at the Xist locus - Nature Structural & Molecular Biology Here Schwämmle et al. develop CRISPR reporter screens to map transcription-factor-regulatory element interactions at the Xist locus, revealing a two-step mechanism integrating developmental and X-dosage signals to initiate X-chromosome inactivation.

⚠️ Paper alert: Using a novel CRISPR screening approach, we mapped the entire regulatory network controlling Xist—key for X-chromosome inactivation.
👉 We discover how sex and development signals are decoded at a single gene locus.

Thanks Joe.

m6A and the NEXT complex direct Xist RNA turnover and X-inactivation dynamics - Nature Structural & Molecular Biology Wei et al. show that the primary function of m6A on the nuclear long noncoding RNA Xist, a master regulator of X inactivation, is to promote RNA degradation. Xist turnover is mediated by the nuclear e...

Thrilled to share our new Brockdorff lab paper at NSMB: we show that the primary role of m6A RNA modification on Xist is to promote RNA degradation. Xist turnover is mediated by the NEXT complex, not PAXT, and is independent of the m6A reader YTHDC1. www.nature.com/articles/s41...

Today, I would like to honor the memory of Roger Y. Tsien, who died on August 24, 2016. His legacy lives with all who use his technologies, including calcium sensors, fluorescent proteins, the acetoxymethyl (AM) ester, & many more! #FluorescenceFriday

New method drop:
HCR-Proxy, a modular proximity labelling approach to profile local proteome composition around RNA at nanoscale, subcompartmental resolution. Thereby we resolved nested nucleolar layers and uncovered the grammar of spatial protein partitioning.

PAL-AI reveals genetic determinants that control poly(A)-tail length during oocyte maturation, with relevance to human fertility - Nature Communications Gene regulation in oocytes relies heavily on poly(A) tail-length changes. Here, the authors develop PAL-AI, a neural network model that predicts tail-length changes, identifies regulatory motifs, and ...

Long-read RNA sequencing of transposable elements from single cells using CELLO-seq - Nature Protocols Single-cell long-read RNA sequencing enables the high-fidelity mapping of single-cell expression data from highly sequence-similar transposable elements to unique genomic loci by correcting errors fro...

Very happy to share our protocols paper for CELLO-seq. This will make single cell long read RNA-seq more accessible and provides analysis guidelines. We hope this helps the #transposon #TEsky community and folks working on #singleCell isoform and allelic #gene expression. doi.org/10.1038/s415...

Selective interaction of the protein SMCHD1 with specific chromatin regions is governed by the loading factor LRIF1 and SMCHD1 ATPase activity The chromosomal protein SMCHD1 is a GHKL ATPase that plays important roles in epigenetic silencing, including on the inactive X chromosome (Xi) and at the D4Z4 macrosatellite linked to regulation of D...

Fresh preprint by @flavia-con.bsky.social from our lab uncovers how SMCHD1 finds & binds chromatin using live-cell single-molecule imaging🔬

She reveals how SMCHD1 dynamically engages chromatin, including the inactive X chromosome, to maintain gene silencing.

Excited to share our new paper on Nature - how Ku accommodates Alu expansion in primates by binding to dsRNA, providing a clue for both the high levels of Ku and its essentiality in human cells. Thank @chaolinzhang @hchung03 @LenaSteckelberg More to come www.nature.com/articles/s41...

I am thrilled to share our latest work, released today 🤩

www-nature-com.insb.bib.cnrs.fr/articles/s41...

It results from years of hard work by the team and long-time collaborators, with special thanks to PhD student Clara Roidor and collaborator Laurène Syx.

Preprint alert. Excited to share our latest work. We demonstrate that the primary function of m6A on Xist is to promote RNA degradation. www.biorxiv.org/content/10.1...

Here it is! Congratuations to @jesskelley.bsky.social @edimitrova.bsky.social @neilblackledge.bsky.social @aleksszczurek.bsky.social and the rest of the team (Maciej, Amy, and Hieu). This was a fab collaboration with Arminja Kettenbach. Also see a lovely complementary paper from Fei Chen's group.

Great thread on our paper from Jan👇

(1st post @BlueSky) Preprint alert🚨a long thread. Cautions in the use of @nanopore sequencing to map DNA modifications: officially reported “accuracy” ≠ reliable mapping in real applications. We performed a critical assessment of nanopore sequencing (across different versions of models) for the 1/n

I've been meaning to write a lengthy thread about our experiences with DNA methylation editing in mouse ESCs if that would be useful (or interesting?) for a niche audience here. tl;dr: it was frustrating but we learned a lot, and it ended with our shiny new pub (1/17) www.nature.com/articles/s41...
