Selective autophagy: ubiquitin-mediated recognition and beyond

Kraft, Claudine, Peter, Matthias, Hofmann, Kay·2010·Nature Cell Biology

Abstract

Eukaryotic cells use autophagy and the ubiquitin-proteasome system as their major protein degradation pathways. Whereas the ubiquitin-proteasome system is involved in the rapid degradation of proteins, autophagy pathways can selectively remove protein aggregates and damaged or excess organelles. Proteasome-mediated degradation requires previous ubiquitylation of the cargo, which is then recognized by ubiquitin receptors directing it to 26S proteasomes. Although autophagy has long been viewed as a random cytoplasmic degradation system, the involvement of ubiquitin as a specificity factor for selective autophagy is rapidly emerging. Recent evidence also suggests active crosstalk between proteasome-mediated degradation and selective autophagy. Here, we discuss the molecular mechanisms that link autophagy and the proteasome system, as well as the emerging roles of ubiquitin and ubiquitin-binding proteins in selective autophagy. On the basis of the evolutionary history of autophagic ubiquitin receptors, we propose a common origin for metazoan ubiquitin-dependent autophagy and the cytoplasm-to-vacuole targeting pathway of yeast.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
