Molecular mechanisms of androgen receptor-mediated gene regulation: structure-function analysis of the AF-1 domain

Open access
McEwan, I J·2004·Endocrine-related cancer

Abstract

The androgen receptor is a ligand-activated transcription factor that binds DNA response elements as a homodimer. Binding sites for the receptor have been identified both upstream and downstream of the transcription start site. Once bound to DNA, the receptor contacts chromatin remodelling complexes, coactivator proteins and components of the general transcription machinery in order to regulate target gene expression. The main transactivation domain, termed AF1, is located within the structurally distinct amino-terminal domain. This region is structurally flexible but adopts a more folded conformation in the presence of the binding partner TFIIF, and this in turn enhances subsequent protein-protein interactions. Thus, there is likely to be a dynamic interplay between protein-protein interactions and protein folding, involving AF1, that is proposed to lead to the assembly and/or disassembly of receptor-dependent transcription complexes.

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

  • AR AF-1 is responsible for p300 recruitment because the majority of the AR-Ab1 binding region is AF-1 (amino acids 142-485).

    “This suggests that AR AF-1 is responsible for p300 recruitment since majority of AR-Ab1 binding region is the AF-1 (aa 142–485) (McEwan, 2004).”

    From Structural Insights of Transcriptionally Active, Full-Length Androgen Receptor Coactivator Complexes (2020) · cites this paper as McEwan, 2004

    The Transcriptional activation section defines AR AF-1 as amino acids 142–485. The Protein-protein interactions section reports that AR acetylation enhances p300 binding, but it does not identify an AR-Ab1 binding region or establish that AF-1 is responsible for p300 recruitment.

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.
