DNA Damage-Induced Activation of p53 by the Checkpoint Kinase Chk2
Abstract
Chk2 is a protein kinase that is activated in response to DNA damage and may regulate cell cycle arrest. We generated Chk2-deficient mouse cells by gene targeting. Chk2 −/− embryonic stem cells failed to maintain γ-irradiation–induced arrest in the G 2 phase of the cell cycle. Chk2 −/− thymocytes were resistant to DNA damage–induced apoptosis. Chk2 −/− cells were defective for p53 stabilization and for induction of p53-dependent transcripts such as p21 in response to γ irradiation. Reintroduction of the Chk2 gene restored p53-dependent transcription in response to γ irradiation. Chk2 directly phosphorylated p53 on serine 20, which is known to interfere with Mdm2 binding. This provides a mechanism for increased stability of p53 by prevention of ubiquitination in response to DNA damage.

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.
