All science arises only because of the shared broader community. I want to especially recognize Rotem Sorek @soreklab.bsky.social Aude Bernheim @audeber.bsky.social our collaborators and the many wonderful labs and scientists in the field bringing together human and bacterial antiviral research!

I am incredibly grateful to my postdoc advisors Jennifer Doudna @doudna-lab.bsky.social and James Berger (berger.med.jhmi.edu) for their constant mentorship and the ideas we started together

"Jane Goodall showed us what a life in science could look like: rigorous discovery paired with fierce advocacy for what you study. She gave the world six decades of groundbreaking research on chimpanzees and their habitats, then turned that knowledge into a global movement for conservation." (1/2)

New research published in @science.org led by @danafarber.bsky.social’s Doug Wassarman and @kranzuschlab.bsky.social reveals new protein chemistry named deazaguanylation that controls activation of immunity.

I am excited to share our new preprint on the CAGE complex, a mysterious hollow protein complex that I first saw years ago while surveying Tetrahymena ciliary lysate www.biorxiv.org/content/10.1... #cilia #protistsonsky 🧬🧪

C. elegans is a real animal and we set out to understand how it comes to have its distinctive biogeography. Its ancestral center of diversity is in the higher elevation forests of Hawaii. Its closest relatives are spread across east Asia. Did they travel from Asia? [Preprint 🧵]

NDG is the initial step in our model of a new form of protein conjugation chemistry. Preprints from Doug + Angela Gao and the Bae lab also link NDG to QatABCD defense, highlighting further roles for Q biosynthetic enzymes in immunity

In phage defense, an N-terminal glycine residue in the substrate protein takes the place of ammonia in canonical Q biosynthetic chemistry to create a protein-nucleobase conjugation modification named N-terminal deazaguanylation or NDG

Why defense islands would encode nucleobase biosynthetic machinery was a mystery. We searched in vain for modified nucleotides as signals in CBASS defense… until Doug surprisingly discovered a Q-like base directly conjugated to the N-terminus of a substrate protein!

In addition to ACGU, "Q" is a modified nucleobase required for tRNA maturation in bacteria, plants, and animals. Since 2020, type IV CBASS phage defense islands were known to encode proteins with homology to the enzymes QueC (Q modification) and TGT (Q installation)

You’ve heard of ubiquitination, meet deazaguanylation: Doug Wassarman in our lab discovered phage defense pathways have co-opted Q nucleobase biosynthetic enzymes to catalyze a new form of protein conjugation chemistry @science.org
