Proteolysis: from the lysosome to ubiquitin and the proteasome

Ciechanover, Aaron·2005·Nature Reviews Molecular Cell Biology

Abstract

How the genetic code is translated into proteins was a key focus of biological research before the 1980s, but how these proteins are degraded remained a neglected area. With the discovery of the lysosome, it was suggested that cellular proteins are degraded in this organelle. However, several independent lines of experimental evidence strongly indicated that non-lysosomal pathways have an important role in intracellular proteolysis, although their identity and mechanisms of action remained obscure. The discovery of the ubiquitin-proteasome system resolved this enigma.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Lysosomes contribute to the enlargement of spines through fusion and donation to dendritic membrane surface area; concurrently, extrusion of cathepsin B into extracellular space initiates a downstream cleavage cascade that promotes remodeling of the extracellular matrix.

    “For example, lysosomes contribute to the enlargement of spines through fusion and thus donation to dendritic membrane surface area; concurrently, extrusion of the protease cathepsin B into the extracellular space initiates a downstream cleavage cascade that promotes remodeling of the extracellular matrix (ECM).32”

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.
