Abstract

The period gene (per) is required for Drosophila melanogaster to manifest circadian (congruent to 24 hr) rhythms. We report here that per protein (PER) undergoes daily oscillations in apparent molecular mass as well as abundance. The mobility changes are largely or exclusively due to multiple phosphorylation events. The temporal profile of the classic short-period form of PER (PERS) is altered in a manner consistent with the mutant strain's behavioral phenotype. As changes in abundance and phosphorylation persist under constant environmental conditions, they reflect or contribute to a free-running rhythm. We suggest that the phosphorylation status of PER is an important determinant in the Drosophila clock's time-keeping mechanism.

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.
