New 🧬✂️ pre-print! We show that paired prime editing can efficiently generate large deletions — even >1 Mb — with high precision and at scale. We use this to perform the first pooled prime deletion screen across the human genome.

Generating long deletions across the genome with pooled paired prime editing screens
Engineered deletions are a powerful probe for studying genome architecture, function, and regulation. Yet, the lack of effective methods to create them in large numbers and at multi-kilobase scale has...

What is a promoter? And how does it work?
We very happy to share our latest work trying to understand enhancer-promoter compatibility.
I am very excited about the results of @blanka-majchrzycka.bsky.social, which changed the way I think about promoters

Enhancer-promoter compatibility is mediated by the promoter-proximal region
Gene promoters induce transcription in response to distal enhancers. How enhancers specifically activate their target promoter while bypassing other promoters remains unclear. Here, we find that the p...

🎇🎄Some holiday reading: Overdue TWEETORIAL on the latest preprint from our lab 🎇🎄
In this work, superstar postdoc @xinhexue.bsky.social combined 2 kinds of pooled CRISPR screens to pinpoint noncoding regulatory elements and the transcription factors that activate these elements.
