40S Ribosome Remodeling Triggers 18S rRNA U-tailing and DIS3L2-dependent Decay

Eliminating defective ribosomes through quality control is essential for accurate protein synthesis. However, the mechanisms that commit ribosomal subunits to decay remain poorly defined. Here, we identify a tandem mechanism in which ubiquitin-mediated ribosome remodeling and 18S rRNA uridylation lead to 40S ribosomal...
