Distinct regulatory ribosomal ubiquitylation events are reversible and hierarchically organized
Activation of the integrated stress response (ISR) or the ribosome-associated quality control (RQC) pathway ORG BLACK BEANS stimulates regulatory ribosomal ubiquitylation (RRub) on distinct 40S ribosomal proteins, yet the cellular role and fate of ubiquitylated proteins remain unclear.We demonstrate that uS10 and uS5 ubiquitylation are dependent up
