Abstract

Nuclear receptors regulate gene expression by direct activation of target genes and inhibition of AP-1. Here we report that, unexpectedly, activation by nuclear receptors requires the actions of CREB-binding protein (CBP) and that inhibition of AP-1 activity is the apparent result of competition for limiting amounts of CBP/p300 in cells. Utilizing distinct domains, CBP directly interacts with the ligand-binding domain of multiple nuclear receptors and with the p160 nuclear receptor coactivators, which upon cloning have proven to be variants of the SRC-1 protein. Because CBP represents a common factor, required in addition to distinct coactivators for function of nuclear receptors, CREB, and AP-1, we suggest that CBP/p300 serves as an integrator of multiple signal transduction pathways within the nucleus.

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?

  • Kamei et al. proposed the term integrator for CBP, suggesting it integrates cellular signals that assemble transcription factors and coactivators and converts them into transcriptional activation.

    “Kamei et al. have coined the term “integrator,” postulating that CBP integrates diverse signals within the cell which culminate in the assembly of transcription factors and coactivators and translates them into transcriptional activation (26).”
  • CBP is a ubiquitous adapter protein that links transcription factors to the basal transcription machinery and is thought to stimulate transcription through contact with RNA polymerase II and histone acetylation.

    “CBP is a ubiquitous adapter protein that mediates contacts between transcription factors and the basal transcription machinery (1,26,33) and is thought to stimulate transcription both by physical contact with the RNA polymerase II complex and through intrinsic histone acetylation activity (4, 33, 52).”

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.
