Abstract

In a search for genes that regulate circadian rhythms in mammals, the progeny of mice treated with N-ethyl-N-nitrosourea (ENU) were screened for circadian clock mutations. A semidominant mutation, Clock, that lengthens circadian period and abolishes persistence of rhythmicity was identified. Clock segregated as a single gene that mapped to the midportion of mouse chromosome 5, a region syntenic to human chromosome 4. The power of ENU mutagenesis combined with the ability to clone murine genes by map position provides a generally applicable approach to study complex behavior in mammals.

  • The Clock mutant mouse has a lengthened endogenous circadian period.

    “The primary genetic model for examining linkage between the circadian and metabolic systems has been the Clock mutant mouse, in which the core circadian gene, Clock, is mutated such that the animal's endogenous circadian period is lengthened (47).”
  • Genetic and biochemical evidence demonstrates that the bHLH-PAS protein CLOCK is required for the proper maintenance of circadian rhythms in mammals.

    “Genetic and biochemical evidence demonstrates that the bHLH-PAS protein CLOCK is required for the proper maintenance of circadian rhythms in mammals.”

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.
