1/ 🚀 AEBP2 isn’t what we thought. You were told that AEBP2 promotes PRC2 activity on chromatin. We found the opposite: the most prevalent AEBP2 isoform inhibits PRC2 activity. 👉 surl.li/cgwqcq A thread 🧵

Our paper in Science is out! @souravagrawal.bsky.social, @rlynn.bsky.social, @susvirkar.bsky.social, and the rest of the team show human RPA is a telomerase processivity factor essential for telomere maintenance. This reshapes our thinking about telomerase regulation. www.science.org/doi/10.1126/...

Now out in Science! Cyclin-dependent kinases (CDKs) are key regulators of the cell cycle. In @vcushing.bsky.social's magnum opus, we use #cryoEM to figure out how the CDK-activating kinase recognises CDKs to fully activate them - a key step in cell cycle control. www.science.org/doi/10.1126/...

New paper on the role of H3K4me3 at enhancers! We (led by Haoming Yu) used dCas9 epigenome editing to add H3K4me3 to intergenic enhancers. This was (1) sufficient to turn up transcription at open, active regions and (2) has no effect on target gene transcription. genesdev.cshlp.org/content/earl...

Excited to share our latest preprint. www.biorxiv.org/content/10.1.... Lead by Lukas, we investigated multiple ways of assessing a TF's sensitivity to chromatin based on genome-wide binding profiles. The developed methods allowed us to quantify chromatin sensitivity across tested TFs.

Vertebrate retrotransposons are the future of gene therapy. But how do they insert their genes? 🔥🔥 Thrilled to share our new work now published with Kathy Collins, @nogaleslab.bsky.social @berkeleymcb.bsky.social where we investigate this with #cryoEM & biochemistry in 🧪 and cells! #RNAsky #TEsky

PRC2 silences genes by adding H3K27me3 at the right spots in the genome. Our model shows how the nucleic acid-binding domain (NBD) of SUZ12 keeps this activity under control, and what happens when you remove it.

Excited to share our work on the specificity of PRC2 subcomplexes in stem cell and differentiation. We show that PRC2.1 and PRC2.2 exhibit distinct H3K27 methylation specificity in human pluripotent stem cells and opposing role in differentiation. Now online at Mol Cell: www.cell.com/molecular-ce...
