Rqc2-mediated modification of ribosome-stalled nascent chains with "CAT tails" promotes formation of insoluble aggregates suggesting that proteins can become specifically marked for aggregation.
Endothelial Differentiation Factor 1 (EDF1) plays a critical role in driving mRNA-specific quality control and global transcriptional responses in response to ribosome collisions.

Genetic screens and functional assays utilizing reporter mRNAs triggering NGD or COMD provide a basis for understanding the unique contributions of each pathway to translation-coupled mRNA decay and contextualizes their effects in the larger cellular process of translation surveillance.
An eukaryotic specific system cooperates with the ribosome quality control pathway to maintain the reading frame during translation of slowly translated sequences.

A hierarchical relationship among highly conserved regulatory ribosomal ubiquitylation events and the presence of antagonistic deubiquitylating enzymes suggests a dynamic ubiquitin code impacts ribosome-associated activities.

Ribosome collisions along an mRNA are shown to recruit factors that prevent additional ribosomes from initiating translation on that mRNA, thereby providing time to resolve the collision.
