Autophagic degradation of ribosomes is promoted by nutrient starvation and inactivation of target of rapamycin complex 1 (TORC1). Here we show that selective autophagic degradation of ribosomes (called ribophagy) after TORC1 inactivation requires the specific autophagy receptor Atg11. Rim15 protein kinase upregulated ribophagy, while it downregulated non-selective degradation of ribosomes.
