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.

Excited to share our discovery of a new programmable RNA-guided DNA-targeting system hiding inside bacteriophages that predates CRISPR. We call it VIPR (Viral Interference Programmable Repeat), and it uses an entirely new logic to find its targets. Thread + link below.

New from Ugrappa Nagalakshmi and Jorge Rodriguez 🌱✂️– Gene editing in plants just got a lot easier! Using engineered TnpB, they demonstrate high-efficiency, heritable, transgene-free editing in plants. (1/7)

Excited to share our first work on protein design! Huge thanks to the entire team, and especially to Bel, Evan, to the Doudna, Jacobsen, Cate, Banfield labs, all co-authors, and my D-lab mates! 💫

Now online at @nature.com we show how the Panoptes defense system protects against viruses that attempt immune evasion - and expands our understanding of the role of oligonucleotides in immunity. Check out this work co-led with @benadler.bsky.social here: www.nature.com/articles/s41...

Excited to finally share this work! We noticed a pair of genes - a nuclease and a protease - shuffles between antiviral systems. We show how proteolysis activates the nuclease, triggering defense in known and unknown immune contexts. tinyurl.com/2uwwy4ty
