🚀 New preprint! @jacobsenucla.bsky.social x @doudna-lab.bsky.social collaboration: High-activity TnpB (Ymu1-WFR) + a multi-gRNA system in TRV enables heritable, tissue-culture-free multiplex editing in plants. Big potential for plant biotech 🧬🌾🌱

New preprint 👉Doudna x Bryant x Jacobsen x Savage collaboration!
Work led by @zehanzhou.bsky.social, I. Saffarian-Deemyad, @honglue.bsky.social, T. Weiss
We dissect how stepwise DNA unwinding gates TnpB genome editing, revealing how unwound DNA states enhance cleavage

How do the ancestors of CRISPR-Cas unwind DNA and how can this lead to better genome editing? With our collaboration between @doudna-lab.bsky.social x @jacobsenucla.bsky.social x Zev Bryant's lab x @savagecatsonly.bsky.social we've uncovered the secrets behind TnpB's dynamics!
The plasmids associated with this paper are available on addgene now! www.addgene.org/browse/artic...
Welcome to the JCC family!
Our paper is finally out in Molecular Cell! 🚀 We uncover why PAM-relaxed Cas9 variants like SpRY are inefficient — they get kinetically trapped during target engagement. Mechanistic insights like this are key to engineering smarter, faster genome editors. Huge thanks to the team! #CRISPR #editing🔬🧬
Now online at Molecular Cell! What makes SpyCas9 such an efficient editor? Read more at: www.cell.com/molecular-ce...
Congrats @honglue.bsky.social, Noor Al-Sayyad, and @kevinwasko.bsky.social!

“What we’ve done here is uncover the secret sauce that makes typical #Cas9 — the original Nobel molecule — so efficient and precise." – Co-first author @honglue.bsky.social of the @doudna-lab.bsky.social on his new paper out today in Molecular Cell

Congratulations! Such an amazing work @erinedoherty.bsky.social
Preprint alert! ✨ In this project that I co-led with @benadler.bsky.social, we show that a miniature CRISPR-Cas10-like enzyme, mCpol, uses a novel inverse signaling mechanism to prevent the spread of viruses that attempt immune evasion by depleting host cyclic nucleotides.
