Degradation of CFTR by the ubiquitin-proteasome pathway

Open access
Ward, Cristina L., Omura, Satoshi, Kopito, Ron R.·1995·Cell

Abstract

Most cases of cystic fibrosis are caused by mutations that interfere with the biosynthetic folding of the cystic fibrosis transmembrane conductance regulator (CFTR), leading to the rapid degradation of CFTR molecules that have not matured beyond the endoplasmic reticulum (ER). The mechanism by which integral membrane proteins including CFTR are recognized and targeted for ER degradation and the proteolytic machinery involved in this process are not well understood. We show here that the degradation of both wild-type and mutant CFTR is inhibited by two potent proteasome inhibitors that induce the accumulation of polyubiquitinated forms of immature CFTR. CFTR degradation was also inhibited by coexpression of a dominant negative ubiquitin mutant and in cells bearing a temperature-sensitive mutation in the ubiquitin-activating enzyme, confirming that ubiquitination is required for rapid CFTR degradation.

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.
