Abstract

Summary The regulatory networks of the DNA damage response (DDR) encompass many proteins and posttranslational modifications. Here, we use mass spectrometry-based proteomics to analyze the systems-wide response to DNA damage by parallel quantification of the DDR-regulated phosphoproteome, acetylome and proteome. We show that phosphorylation-dependent signaling networks are regulated more strongly compared to acetylation. Among the phosphorylated proteins identified are many putative substrates of DNA-PK, ATM and ATR kinases, but a majority of phosphorylated proteins do not share the ATM/ATR/DNA-PK target consensus, suggesting an important role of downstream kinases in amplifying DDR signals. We show that the splicing-regulator phosphatase PPM1G is recruited to sites of DNA damage, while the splicing-associated protein THRAP3 is excluded from these regions. Moreover, THRAP3 depletion causes cellular hypersensitivity to DNA damaging agents, thus suggesting an important link between RNA metabolism and DNA repair. Our results broaden the knowledge of DNA damage signaling networks and identify novel components of the DDR.

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.
