We investigate interesting E3 mechanisms at the frontline between virus and cell, with some virology thrown in for good measure. Ub-er fun! At the MRC-University of Glasgow Centre for Virus Research. https://thefletcherlab.co.uk

Our work on the role of Ufmylation on ribosome quality control on the ER is out! Great work of two terrific first authors Milica and @alessandrick.bsky.social together with our wonderful collaborators, the one and only Dagdas lab @plantophagy.bsky.social!

🆕 publication! The @gekaragoz.bsky.social lab shows how cells clear stalled ribosomes at the ER, preventing harmful 'traffic jams' during protein synthesis🚦Their new @embojournal.org study reveals how quality control and UFMylation team up to keep translation moving ➡️ tinyurl.com/2czj8fvp

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

Squair et al. show that ZNFX1 restricts ssRNA virus replication by integrating SF1 helicase activity with dual E3 ligase mechanisms. ATP-dependent RNA binding activates E3 function, driving self-propa...

Hello world! I am excited to announce my lab is open at the University of Utah in the Department of Biochemistry. We are looking for scientists at all levels interested in studying host-virus interactions in both bacteria and animals. Come join us in beautiful Utah! (photo is 10 steps from lab)

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...

Our work on the Panoptes antiphage system is published! Here we find that Panoptes "watches" the cytosol for phage immune evasion proteins–captured in this illustration by Clair Huffine of Insight Illustrations. A beautiful example of the effector triggered immunity paradigm.

Allosteric activation of a ubiquitin ligase by an internal kinase domain! Congratulations to our team member Thornton Fokkens for this fascinating discovery in a neglected disease area with strong therapeutic need. Many thanks to all our great collaborators! www.sciencedirect.com/science/arti...

Stringent control of ubiquitylation is a central requirement of signaling specificity in eukaryotes. Here, we discover a domain module integrating pro…
