The DNA-dependent Protein Kinase Catalytic Subunit Phosphorylation Sites in Human Artemis
Open accessAbstract
Artemis protein has irreplaceable functions in V(D)J recombination and nonhomologous end joining (NHEJ) as a hairpin and 5' and 3' overhang endonuclease. The kinase activity of the DNA-dependent protein kinase catalytic subunit (DNA-PKcs) is necessary in activating Artemis as an endonuclease. Here we report that three basal phosphorylation sites and 11 DNA-PKcs phosphorylation sites within the mammalian Artemis are all located in the C-terminal domain. All but one of these phosphorylation sites deviate from the SQ or TQ motif of DNA-PKcs that was predicted previously from in vitro phosphorylation studies. Phosphatase-treated mammalian Artemis and Artemis that is mutated at the three basal phosphorylation sites still retain DNA-PKcs-dependent endonucleolytic activities, indicating that basal phosphorylation is not required for the activation. In vivo studies of Artemis lacking the C-terminal domain have been reported to be sufficient to complement V(D)J recombination in Artemis null cells. Therefore, the C-terminal domain may have a negative regulatory effect on the Artemis endonucleolytic activities, and phosphorylation by DNA-PKcs in the C-terminal domain may relieve this inhibition.

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.
