The ribosome synchronizes folding and assembly to promote oligomeric protein biogenesis
Large oligomeric proteins constitute a major fraction of proteomes, but are difficult
to refold in vitro, raising the question of how cells direct their biogenesis. Roeselová

When RNA Degradation 🤝 meets 🤝 Protein Degradation! tinyurl.com/E3TDMD In a collaboration of @bartellab.bsky.social and Schulman lab, we show that, in target-directed microRNA degradation (TDMD), 2-RNA-factors recruit an E3 ligase and induce the degradation of not only a protein but also RNA (1/5).

ER-associated single-capped vaults are surprising and really cool!🤩 Some even contain ribosomes. Vault function is still mysterious but a role in protein quality control seems plausible.
Also great to see Dicty in the #TeamTomo spotlight! #ProtistsOnSky @kgeissler.bsky.social @becklab.bsky.social 🧪

How does messenger RNA (mRNA) get out of the nucleus to become a protein? Eukaryotic mRNA is packaged, exported, and then translated in the cytoplasm. But how do these steps work? And what are open questions? Check out our new review for our take: www.annualreviews.org/content/jour... (1/3)
