Abstract

The corepressor SMRT mediates repression by thyroid hormone receptor (TR) as well as other nuclear hormone receptors and transcription factors. Here we report the isolation of a novel SMRT-containing complex from HeLa cells. This complex contains transducin β-like protein 1 (TBL1), whose gene is mutated in human sensorineural deafness. It also contains HDAC3, a histone deacetylase not previously thought to interact with SMRT. TBL1 displays structural and functional similarities to Tup1 and Groucho corepressors, sharing their ability to interact with histone H3. In vivo, TBL1 is bridged to HDAC3 through SMRT and can potentiate repression by TR. Intriguingly, loss-of-function TRβ mutations cause deafness in mice and humans. These results define a new TR corepressor complex with a physical link to histone structure and a potential biological link to deafness.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • 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.”

    From Structure of Hdac3 Bound to Co-Repressor and Inositol Tetraphosphate (2012) · cites this paper as [24]

    The Abstract (page not provided) identifies HDAC3 in a purified core SMRT complex without other HDACs. “SMRT serves as a platform for HDAC3 and TBL1” (page not provided) reports direct HDAC3 interaction with SMRT RD2 and strong interaction with N-CoR RD2. The paper does not identify either region as a conserved deacetylase-activation domain (DAD), or establish that HDAC3 is uniquely recruited to SMRT/N-CoR complexes in general. (LLM, conf=0.87)

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.
