Abstract

Asparagine-803 in the C-terminal transactivation domain of human hypoxia-inducible factor (HIF)-1 α-subunit is hydroxylated by factor inhibiting HIF-1 (FIH-1) under normoxic conditions causing abrogation of the HIF-1α/p300 interaction. NMR and other analyses of a hydroxylated HIF fragment produced in vitro demonstrate that hydroxylation occurs at the β-carbon of Asn-803 and imply production of the threo-isomer, in contrast with other known aspartic acid/asparagine hydroxylases that produce the erythro-isomer.

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

  • Hypoxia encourages interaction between C-TAD and CBP/p300 through inhibition of oxygen-dependent hydroxylation of N803, resulting in transcriptional activation of target genes.

    “Alternatively, hypoxia encourages this interaction through the inhibition of oxygen dependent hydroxylation of N803, resulting in transcriptional activation of the target genes32, 33, 34.”

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.
