Abstract

We used positional cloning to identify the circadian Clock gene in mice. Clock is a large transcription unit with 24 exons spanning approximately 100,000 bp of DNA from which transcript classes of 7.5 and approximately 10 kb arise. Clock encodes a novel member of the bHLH-PAS family of transcription factors. In the Clock mutant allele, an A-->T nucleotide transversion in a splice donor site causes exon skipping and deletion of 51 amino acids in the CLOCK protein. Clock is a unique gene with known circadian function and with features predicting DNA binding, protein dimerization, and activation domains. CLOCK represents the second example of a PAS domain-containing clock protein (besides Drosophila PERIOD), which suggests that this motif may define an evolutionarily conserved feature of the circadian clock mechanism.

  • The Clock gene is one of the central components of the circadian machinery.

    “This includes the identification of the Clock gene which is one of the central components of the circadian machinery (King et al., 1997).”
  • These CLOCK mutant mice have a point mutation in the CLOCK gene caused by ENU mutagenesis that results in a dominant-negative protein.

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.
