The role of CLIP and cohibin complexes in micronucleophagy. Nucleolar proteins, rDNA, and the cohibin complex are associated at nucleoli under growing conditions, while the CLIP complex is distributed over the entire inner side of the nuclear membrane. TORC1 inactivation triggers the association of nucleolar proteins with part of the CLIP complexes and their subsequent targeting to the NVJ, where they are included into the forming intravacuolar invagination. The pinch-off of this protrusion leads to the vacuolar turnover of both nucleolar proteins and the CLIP complex. In contrast, rDNA and cohibin remain associated and get separated from the nucleolar proteins to remain protected from micronucleophagic degradation.
