Abstract

The majority of regulated protein degradation in eukaryotes is accomplished by the 26S proteasome, the large proteolytic complex responsible for removing regulatory proteins and damaged proteins. Proteins are targeted to the proteasome by ubiquitination, and degradation is initiated at a disordered region within the protein. The ability of the proteasome to precisely select which proteins to break down is necessary for cellular functioning. Recent studies reveal the subtle mechanisms of substrate recognition by the proteasome - diverse ubiquitin chains can act as potent proteasome targeting signals, ubiquitin receptors function uniquely and cooperatively, and modification of initiation regions modulate degradation. Here, we summarize recent findings illuminating the nature of substrate recognition by the proteasome.

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.
