Fresh out of the oven, our collaboration with the Kopito Lab - UFL1(E3) modifies, binds to, and dissociates the 60S subunit from the Sec61 translocon! #ribosome #cryoEM

For a more detailed look, check out the paper now👉

Otu2 can bind to 40S during cytoplasmic ribosome biogenesis and all stages between ribosome recycling and start-codon recognition, but becomes a highly specific enzyme for translational reset during recycling/(re)initiation by removing mono-ubiquitin present on eS7.

We also solved the crystal structure of the OTU domain of Otu2 and showed how it recognizes and deubiquitinates eS7 with Lys83-linked monoubiquitin. This binding mode explains the discrimination against 80S ribosomes and the specificity for mono-ubiquitinated eS7 on 40S.

We used cryo-EM to visualize native and reconstituted Otu2-bound ribosomal complexes at different stages of translation. We found that Otu2 binds to 40S subunits mainly between ribosome recycling and initiation stages.

Otu2 is a deubiquitinating enzyme that removes ubiquitin from eS7, a ribosomal protein of the 40S subunit. Ubiquitination of eS7 by Not4 E3 ligase occurs during active translation and affects translation efficiency. However, the role and mechanism of Otu2 are poorly understood.

🎉We are thrilled to share our exciting new collaboration with @inada_lab and @jingdongcheng on how Otu2 recognizes and deubiquitinates 40S ribosomes after translation. Here is a thread with the most interesting findings:👇 #ribosome #ubiquitin #cryoEM

The Ski2-like helicase 1 subunit applies a pulling force on the mRNA which causes RQT to swivel between two conformations. This leads to the destabilization of the 40S subunit, resulting in subunit dissociation of the leading ribosome.

The ribosome-associated quality control pathway is activated when ribosomes collide during persistent stalling. The RQT complex splits the stalled ribosome, thus clearing harmful traffic jams in the cell.

Keeping up the momentum, we're excited to share the final version of our story about RQT-driven ribosomal splitting 🎉 🎉 Shout out to @KaBe__01, @ThomasB08006066, @inada_lab and everyone involved! Read on to learn more👇🏻👇🏻👇🏻 #cryoEM #ribosome #RQT.
