New pre-print 📣 “Undruggable” cancer mutations remain very hard to target with current modalities. What if we could instead sense mutant transcripts and convert that recognition into selective cell killing? Check out this work led by postdoc Jingkun Zeng: www.biorxiv.org/content/10.6...

We present VIPR, a phage-encoded RNA-guided system that recognizes DNA with a noncontiguous code unlike CRISPR. Tiny, programmable, possibly ancestral to CRISPR immunity; VIPR is built around a striking RNA-DNA-DNA triplex.

Truly some of the most innovative papers I’ve read in the field- here’s a set of 2 papers from the lab that biochemically and structurally profile an ancestor of the type 1 CRISPR-Cas proteins!!! www.biorxiv.org/content/10.6... www.biorxiv.org/content/10.6...

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!

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 www.biorxiv.org/content/10.6...

✨New preprint! 🧵1/4 Excited to share our work on AI-guided design of minimal RNA-guided nucleases. Amazing work by @petrskopintsev.bsky.social @isabelesain.bsky.social @evandeturk.bsky.social et al! Multi-lab collaboration @banfieldlab.bsky.social @jhdcate.bsky.social @jacobsenucla.bsky.social🧬 🔗👇

1/10 Genome maintenance by telomerase is a fundamental process in nearly all eukaryotes. But where does it come from? Today, we report the discovery of telomerase homologs in a family of antiviral RTs, revealing an unexpected evolutionary origin in bacteria. www.biorxiv.org/content/10.1...

Excited to share our new preprint co-led by @jnoms.bsky.social! Here we reveal an exceptional diversity of viral 2H phosphodiesterases (PDEs) that enable immune evasion by selectively degrading oligonucleotide-based messengers. This 2H PDE fold has evolved striking substrate breath & specificity.

1/10 New pre-print(s) from the Sternberg Lab in collaboration with Leifu Chang's Lab! We uncover the unprecedented molecular mechanism of CRISPR-Cas12f-like proteins, which drive RNA-guided transcription independently of canonical promoter motifs. Full story here: www.biorxiv.org/content/10.1...

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🔬🧬

Glad to welcome Democratic Vice Chair @tedlieu.bsky.social to CA-12 today. We toured labs at @ucberkeleyofficial.bsky.social and discussed how the Trump administration's attacks on NIH funding endangers decades of leading research and scientific work.
