Abstract

Regulated proteolysis plays important roles in cell physiology as well as in pathological conditions. In most of the cases, regulated proteolysis is carried out by the ubiquitin‐ and proteasome‐dependent proteolytic system, which is also in charge of the bulk of cytoplasmic proteolysis. However, apoptosis or the process of programmed cell death is regulated by a different proteolytic system, i.e. by caspases, a family of specialized cysteine proteases. Nevertheless, there is plenty of evidence of a crosstalk between the apoptotic pathways and the ubiquitin and proteasome system, whose function in apoptosis appears to be very complex. Proteasome inhibitors induce apoptosis in multiple cell types, while in other they are relatively harmless or even prevent apoptosis induced by other stimuli. Proteasomes degrade specific proteins during apoptosis, but on the other hand some components of the proteasome system are degraded by caspases. The knowledge about the involvement of the ubiquitin‐ and proteasome‐dependent system in apoptosis is already clinically exploited, since proteasome inhibitors are being tested as experimental drugs in the treatment of cancer and other pathological conditions, where manipulation of apoptosis is desirable.

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.
