Receptor clustering is a common theme in viral detection, but whether detection directly hinders genome replication is less clear. Excited to share the Z in RZ-type E3s: ZNFX1 is an RNA helicase that builds ubiquitin chains leading to aggregates that ensnare viral RNA. www.cell.com/molecular-ce...
ZNFX1 uses two-component ubiquitin circuitry to quarantine viral RNA

CBASS is a cyclic nucleotide-based antiviral system in bacteria that is related to cGAS-STING signaling in animals. One of the big questions is how CBASS is activated during phage infection? We made some progress on this during my final year in the Kranzusch lab. www.biorxiv.org/content/10.6...

Super new paper from @ubch-alice.bsky.social and Danny Huang @cruk-si.bsky.social – a great deal of hard work and development behind this story. From a technical perspective, this reads as a primer for tapping 'unconventional' E3s. Very well done Alice and team!
My first-author paper is out in @chemicalscience.rsc.org from my time in Professor Danny Huang’s laboratory @cruk-si.bsky.social. We showed that CBL can be used as a degrader E3 to target the “undruggable” eIF4E. pubs.rsc.org/en/content/a...
