Our paper is now out in @natcellbio.nature.com! @craigmcrews.bsky.social www.nature.com/articles/s41... We identify a new regulator of the quality control system that protects one of nature's most important molecular machines: the ribosome. QC failure → unmitigated metabolic stress & cell death.

Very pleased to share with you our novel review on regulation of protein secretion by ER and Golgi stress responses ! lnkd.in/ekt-ri37 Thank you to support from @OligocyteBretagne @INCR @CentreEugèneMarquis @INSERM @LigueContreLeCancer

Congrats @tonyavril.bsky.social and team 🤩 ... well done 👏

This project started with confusion 🤔 www.nature.com/articles/s41... Loss of LUBAC or OTULIN causes severe inflammatory disease. But patients also show clear metabolic defects. Neither LUBAC nor OTULIN had been linked to metabolic regulation. So where do these metabolic manifestations come from?
