Abstract

Kinases in the phosphoinositide three-kinase-related kinase (PIKK) family include ATM (ataxia-telangiectasia mutated), ATR (ATM- and Rad3-related), DNA-PKcs (DNA-dependent protein kinase catalytic subunit), mTOR (mammalian target of rapamycin), and SMG1 (suppressor with morphological effect on genitalia family member). These atypical protein kinases regulate DNA damage responses, nutrient-dependent signaling, and nonsense-mediated mRNA decay. This review focuses on the mechanisms regulating the PIKK family with a strong emphasis on the DNA damage regulated kinases. We outline common regulatory themes and suggest how discoveries about the regulation of one PIKK can be informative for the other family members.

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.
