Oligo(uridine) tailing and exonucleolytic decay drive 40S ribosome degradation in response to stress
Stresses like starvation trigger degradation of mature 40S ribosomes, requiring the coordinated breakdown of large and stable RNA-protein complexes. The atypical kinase RIOK3 orchestrates degradation by binding ubiquitylated 40S ribosomes and promoting rRNA decay. However, the mechanisms and factors
