Abstract

The only reported role for the conjugation of the NEDD8 ubiquitin-like molecule is control of the activity of SCF ubiquitin ligase complexes. Here, we show that the Mdm2 RING finger E3 ubiquitin ligase can also promote NEDD8 modification of the p53 tumor suppressor protein. Mdm2 is itself modified with NEDD8 with very similar characteristics to the autoubiquitination activity of Mdm2. By using a cell line (TS-41) with a temperature-sensitive mutation in the NEDD8 conjugation pathway and a p53 mutant that cannot be NEDDylated (3NKR), we demonstrate that Mdm2-dependent NEDD8 modification of p53 inhibits its transcriptional activity. These findings expand the role for Mdm2 as an E3 ligase, providing evidence that Mdm2 is a common component of the ubiquitin and NEDD8 conjugation pathway and indicating the diverse mechanisms by which E3 ligases can control the function of substrate proteins.

  • Mdm2 promotes conjugation of NEDD8 to itself and to p53.

    “Mdm2 also promotes the conjugation of NEDD8 (another Ubl molecule), to itself and to p53 [124].”

  • Replacing these lysines with arginine leads to increased p53 transcriptional activity in vitro, suggesting that NEDDylation of p53 inhibits its function.

  • Mdm2-mediated NEDDylation occurs at a restricted subset of p53 lysines: K370, K372, and K373.

    “Although Mdm2 ubiquitylates several C-terminal lysines of p53, Mdm2-mediated NEDDylation occurs at a restricted subset of them (K370, K372, K373).”

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.
