Abstract

In eukaryotic cells, the ubiquitin-proteasome pathway is the major mechanism for targeted degradation of proteins. We show that, in F9 cells and in transfected COS-1 cells, the nuclear retinoid receptors, retinoic acid receptor gamma2 (RARgamma2), RARalpha1, and retinoid X receptor alpha1 (RXRalpha1) are degraded in a retinoic acid-dependent manner through the ubiquitin-proteasome pathway. The degradation of RARgamma2 is entirely dependent on its phosphorylation and on its heterodimerization with liganded RXRalpha1. In contrast, RARalpha1 degradation can occur in the absence of heterodimerization, whereas it is inhibited by phosphorylation, and heterodimerization reverses that inhibition. RXRalpha1 degradation is also modulated by heterodimerization. Thus, each partner of RARgamma/RXRalpha and RARalpha/RXRalpha heterodimers modulates the degradation of the other. We conclude that the ligand-dependent degradation of RARs and RXRs by the ubiquitin-proteasome pathway, which is regulated by heterodimerization and by phosphorylation, could be important for the regulation of the magnitude and duration of the effects of retinoid signals.

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.
