Activation of the Cellular DNA Damage Response in the Absence of DNA Lesions

Open access

Abstract

The cellular DNA damage response (DDR) is initiated by the rapid recruitment of repair factors to the site of DNA damage to form a multiprotein repair complex. How the repair complex senses damaged DNA and then activates the DDR is not well understood. We show that prolonged binding of DNA repair factors to chromatin can elicit the DDR in an ATM (ataxia telangiectasia mutated)– and DNAPK (DNA-dependent protein kinase)–dependent manner in the absence of DNA damage. Targeting of single repair factors to chromatin revealed a hierarchy of protein interactions within the repair complex and suggests amplification of the damage signal. We conclude that activation of the DDR does not require DNA damage and stable association of repair factors with chromatin is likely a critical step in triggering, amplifying, and maintaining the DDR signal.

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.
