Abstract

The corepressors N-CoR and SMRT partner with histone deacetylases (HDACs) in diverse repression pathways. We report here that GPS2, a protein involved in intracellular signaling, is an integral subunit of the N-CoR-HDAC3 complex. We have determined structural motifs that direct the formation of a highly stable and active deacetylase complex. GPS2 and TBL1, another component of the N-CoR-HDAC3 complex, interact cooperatively with repression domain 1 of N-CoR to form a heterotrimeric structure and are indirectly linked to HDAC3 via an extended N-CoR SANT domain that also activates latent HDAC3 activity. More importantly, we show here that the N-CoR-HDAC3 complex inhibits JNK activation through the associated GPS2 subunit and thus could potentially provide an alternative mechanism for hormone-mediated antagonism of AP-1 function.

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

Claims the paper makes

We couldn’t retrieve this paper’s full text, 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?

  • The DAD both recruits and activates HDAC3.

    “The DAD both recruits and activates HDAC310-12.”
  • HDACs 1, 2 and 3 require association with large multisubunit corepressor complexes for maximal activity.

    “HDACs 1, 2 and 3 require association with large multisubunit corepressor complexes for maximal activity7-12.”
  • HDAC3 appears to be uniquely recruited to the SMRT/NCoR complex, where it interacts with a conserved deacetylase-activation-domain (DAD) within SMRT or NCoR.

    “In contrast, HDAC3 appears to be uniquely recruited to the SMRT/NCoR complex where it interacts with a conserved deacetylase-activation-domain (DAD) within SMRT or NCoR8,10,12,24,25,26.”

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.
