Abstract

E3 ubiquitin ligases are important in both innate and adaptive immunity. Here we report that Nrdp1, an E3 ubiquitin ligase, inhibited the production of proinflammatory cytokines but increased interferon-beta production in Toll-like receptor-triggered macrophages by suppressing adaptor MyD88-dependent activation of transcription factors NF-kappaB and AP-1 while promoting activation of the kinase TBK1 and transcription factor IRF3. Nrdp1 directly bound and polyubiquitinated MyD88 and TBK1, which led to degradation of MyD88 and activation of TBK1. Knockdown of Nrdp1 inhibited the degradation of MyD88 and the activation of TBK1 and IRF3. Nrdp1-transgenic mice showed resistance to lipopolysaccharide-induced endotoxin shock and to infection with vesicular stomatitis virus. Our data suggest that Nrdp1 functions as both an adaptor protein and an E3 unbiquitin ligase to regulate TLR responses in different ways.

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?

  • Parkin-deficient mice and mice expressing a dominant negative form of Nrdp1 are not reported to have significant neurodegenerative disease.

    “Importantly, parkin-deficient mice and mice expressing a dominant negative form of Nrdp1 are not reported to have significant neurodegenerative disease171819.”
  • Lack of reported neurodegeneration in parkin-deficient and Nrdp1 mutant mice makes it unlikely that the Nrdp1 interaction explains the finding of neurodegeneration in Clec16a mutant mice.

    “The lack of reported neurodegeneration in parkin-deficient and Nrdp1 mutant mice171819 makes it unlikely that this interaction explains our finding of neurodegeneration in Clec16a mutant mice.”

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.
