Autophagy
J Cell Sci (2021) 134 (4): jcs253682.
Published: 26 February 2021
..., the cell is not completely degraded through autophagy, implying the existence of some kind of termination mechanism. In the yeast Saccharomyces cerevisiae , autophagy is terminated after 10–12 h of nitrogen starvation. In this study, we found that termination is mediated by re-phosphorylation of Atg13...

... find that in Saccharomyces cerevisiae budding yeast, Cdc48 accumulates during cellular stress at intranuclear protein quality control sites (INQ). We show that Cdc48 function is required to suppress INQ formation under non-stress conditions and to promote recovery following genotoxic stress. Cdc48...

... endocytic cargo. To test this idea, we analyzed the yeast adaptor protein Sla1, which binds membrane proteins harboring the endocytic signal NPFxD via the Sla1 SHD1 domain. Consistently, SHD1 domain point mutations that disrupted NPFxD binding caused a proportional reduction in Sla1–GFP recruitment to...
