Expanded Roles for Chk1 in Genome Maintenance

Open access
Enders, Greg H.·2008·Journal of Biological Chemistry

Abstract

Chk1 is a conserved kinase that imposes cell cycle delays in response to impediments to DNA replication. Recent experiments have further defined effects of Chk1 on the activity of mammalian origins of DNA replication and progression of replication forks. Moreover, Chk1 now appears to help defend genomic integrity through effects on several other pathways, including Fanconi anemia proteins, the mitotic spindle, and transcription of cell cycle-related genes. These findings can account for the requirement for Chk1 in normal proliferating cells of the early embryo and suggest the potential for diverse effects of Chk1 inhibition in cancer therapy.

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.
