Excited to share the first work from my new lab describing how LigIIIα catalyzes nick ligation within the nucleosome during the terminal step of BER/SSBR. Hard to believe the lab performed our first experiment just over a year ago! www.biorxiv.org/content/10.6...

Check out the final version of this work, out today! @natcomms.nature.com www.nature.com/articles/s41...

Ahmad Jomaa@jomaalab.bsky.social · last yr.

Check out our new preprint on the discovery of a molecular switch in NAC that mediates nascent chain sorting on the ribosome and prevents mitochondrial protein mistargeting by SRP. A great collaboration with the Shan Lab @Caltech and the Qi Lab @UVA: www.biorxiv.org/content/10.1...

Congratulations and welcome to the newest members of the #ACSBIOL Executive Committee! @freudlab.bsky.social, @doc-jlmeier.bsky.social, @tmweaver.bsky.social, @ebraselmann.bsky.social

Check out the perspective my lab wrote with @freudlab.bsky.social. We provide our perspective on recent work describing the structural basis of chromatin-based base excision repair!

Bret Freudenthal@freudlab.bsky.social · 9mo ago

🎉 Joint paper from the Freudenthal and @tmweaver.bsky.social Labs! Abbey Vito’s first publication discusses a tug-of-war between BER enzymes and chromatin for access to damaged DNA, a battle central to genome stability. Built on Tyler's foundational work! tinyurl.com/ywkt2bt5

See our paper “Mechanism of trinucleotide repeat expansion by MutSβ-MutLγ and contraction by FAN1”. Using biochemistry, we show how DNA incisions by the MutLγ nuclease can lead to expansions, and how expansion is prevented by FAN1. Well done Issam and Valentina! www.nature.com/articles/s41...

The final piece of my postdoctoral work in the @freudlab.bsky.social was recently published! Quite amazing what this small little repair polymerase can do to fill 1-nt gaps in chromatin. www.nature.com/articles/s41...

Is chromatin ordered or disordered? It all depends on the linker DNA length. Check our latest work with Mike Rosen and Sy Redding. We explore how changes in linker DNA length (as small as 1 bp) fine-tune chromatin structure, between order and disorder, and the properties of chromatin droplets

Our preprint from earlier this year on the oxidation-induced mutational landscape in human cells was just published! www.nature.com/articles/s41... I’m still amazed how much chromatin structure impacts oxidation-induced mutagenesis. Our cryo-EM contribution in this work provides a glimpse into why!
