The Ubiquitin System, an Immense Realm
Abstract
Among the functions of intracellular proteolysis are the elimination of misfolded or otherwise abnormal proteins; the maintenance of amino acid pools in cells affected by stresses, such as starvation; and the generation of protein fragments that act as hormones, antigens, or other effectors. Many intracellular proteins are either conditionally or constitutively short-lived, with in vivo half-lives that can be as brief as a few minutes. In some cases, a proteolytic pathway targets and destroys a protein cotranslationally, i.e., an emerging polypeptide chain can be degraded while it is still a ribosome-associated \npeptidyl-tRNA (1, 2). The regulated and processive degradation of intracellular proteins is carried out largely by the ubiquitin (Ub)- proteasome system (Ub system), in conjunction with molecular chaperones, autophagy, and lysosomal proteolysis. Other mediators of \nintracellular protein degradation include proteases such as caspases, calpains, and separases. These and other nonprocessive proteases can function as “upstream” components of the Ub system, generating protein fragments that are targeted and degraded to short peptides by Ub-mediated pathways. Proteins that are damaged, misfolded, or otherwise abnormal are often recognized as such and selectively destroyed by the Ub system. Physiologically \nimportant exceptions include conformationally perturbed proteins and/or their aggregates that are harmful but cannot be efficaciously repaired or removed. The resulting proteotoxicity underlies both aging and specific diseases, \nincluding neurodegeneration.

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.
