Abstract

We have mapped the distribution of the major and minor DNase I-hypersensitive sites in the human "beta-like-globin" gene domain. The minor DNase I-hypersensitive sites map close to the 5' end of each of the beta-like-globin genes. Their presence is specifically associated with the transcription of the immediate downstream beta-like-globin genes. The major DNase I-hypersensitive sites map in what appear to be the 5' and 3' boundary areas of the human beta-like-globin gene domain, a region estimated to span at least 90 kilobases of DNA. These major sites are present in various erythroid cells, which express predominantly either the embryonic, the fetal, or the adult beta-like-globin genes, and seem to be involved in defining the active beta-like-globin genes domain in cells of erythroid lineage. The four major DNase I-hypersensitive sites in the 5' boundary area, when correlated with sequencing data, are shown to be located in DNA regions containing enhancer core-like sequences and alternating purine and pyrimidine bases.

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

  • The mammalian β-globin locus developmental β-globin genes are regulated by a powerful tissue-specific enhancer known as a locus control region (LCR).

    “These models were initially applied to the mammalian β-globin locus, in which the developmental β-globin genes are regulated by a powerful tissue-specific enhancer known as a locus control region (LCR) [254–257].”

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.
