A good day to remember John Gurdon’s school report from his biology master at Eton

Happy 10th year birthday to the amazing Bücker lab! Many more fun, successful years to come!

GCN1 couples GCN2 to ribosomal state to initiate amino acid response pathway signaling During nutrient deprivation, activation of the protein kinase GCN2 regulates cell survival and metabolic homeostasis. In addition to amino acid stress, GCN2 is activated by a variety of cellular stres...

Beautiful reconstitution of amino acid stress-dependent ISR activation by my @harvardcellbio.bsky.social colleagues presenting a unifying mechanism for GCN2 activation, which requires ribosome collisions and is enhanced by cognate uncharged tRNA in the A site! www.science.org/doi/10.1126/...

Fantastic opportunity. Vienna rocks!

An ancient and essential miRNA family controls cellular interaction pathways in C. elegans A microRNA that arose at the origin of eumetazoans regulates cell adhesion and signaling in C. elegans through conserved targets.

Our work on the function of miR-51/miR-100 is out! miR-100 is widely conserved across eumetazoans but its function has been mysterious. Emilio Santillán found in worms it regulates signaling and extracellular matrix genes, some of which seem to be conserved targets! www.science.org/doi/10.1126/...

Another amazing story! Congrats Dan and the Clausen lab!

Glad to share the final version of our story about the UBR4 complex, an E4 ligase protein quality control hub @science.org. Now with more cryo-EM structures and a deeper dive into substrate recognition, especially escaped mitochondrial proteins @clausenlab.bsky.social www.science.org/doi/10.1126/...

Great work! Congrats, Dan!!!

A split-site E3 ligase mechanism enables ZNFX1 to ubiquitinate and cluster single-stranded RNA into ubiquitin-coated nucleoprotein particles Grabarczyk et al. show the structure and mechanism of a non-canonical ubiquitin ligase, which is activated through nucleic-acid-induced oligomerization and is critical for cell survival during immune ...

Happy to share our work on the structure and function of the unusual E3 ligase ZNFX1 @cp-cell.bsky.social. It uses a nucleic acid-activated transthiolation mechanism, ubiquitinating and clustering RNA to protect cells in an immune response. @clausenlab.bsky.social

📢 New preprint: Aromatic Ring Flips Reveal Reshaping of Protein Dynamics in Crystals and Complexes.

We addressed a long-standing question that people debated already in the 1970s - but it still remained open:
Do proteins in crystals move as they do in solution? We used ring flips to find out.

Congrats, Anna!!! Beautiful work!

Exciting new work from Dagdas lab! Congrats to Alibek and all the team!

The EMC acts as a chaperone for membrane proteins - Nature Communications Membrane proteins are essential for any cell but difficult to fold. Here, the authors show that the EMC acts as a chaperone for membrane proteins. They dissect client recognition and provide a molecul...

Excited to share our latest study in @natcomms.nature.com , where we characterize the chaperone function of the ER membrane protein complex (EMC)—supporting membrane protein biogenesis beyond insertion!
