Neuronal ribosomes exhibit dynamic and context-dependent exchange of ribosomal proteins

open access: yesNature Communications, 2021
Owing to their morphological complexity and dense network connections, neurons modify their proteomes locally, using mRNAs and ribosomes present in the neuropil (tissue enriched for dendrites and axons).

Evolutionary shift toward protein-based architecture in trypanosomal mitochondrial ribosomes

open access: yesScience, 2018
Structure of the largest, most complex ribosome Ribosomes are two-subunit ribonucleoprotein assemblies that catalyze the translation of messenger RNA into protein. Ribosomal RNAs (rRNAs) play key structural and functional roles. Ramrath et al. report the

Mutant Huntingtin stalls ribosomes and represses protein synthesis in a cellular model of Huntington disease

open access: yesNature Communications, 2021
The polyglutamine expansion of huntingtin (mHTT) causes Huntington disease (HD) and neurodegeneration, but the mechanisms remain unclear. Here, we found that mHtt promotes ribosome stalling and suppresses protein synthesis in mouse HD striatal neuronal ...

Structure of Gcn1 bound to stalled and colliding 80S ribosomes

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2020
Significance There is growing evidence that collisions between ribosomes represent a cellular signal for activating multiple stress pathways, such as ribosome-associated quality control (RQC), the ribotoxic stress response, and the integrated stress ...

Structure and function of yeast Lso2 and human CCDC124 bound to hibernating ribosomes

open access: yesbioRxiv, 2020
Cells adjust to nutrient deprivation by reversible translational shut down. This is accompanied by maintaining inactive ribosomes in a hibernation state, where they are bound by proteins with inhibitory and protective functions.

Collided ribosomes form a unique structural interface to induce Hel2‐driven quality control pathways

open access: yesEMBO Journal, 2019
Ribosome stalling triggers quality control pathways targeting the mRNA (NGD: no‐go decay) and the nascent polypeptide (RQC: ribosome‐associated quality control). RQC requires Hel2‐dependent uS10 ubiquitination and the RQT complex in yeast.
