Phosphorylation of Artemis following irradiation‐induced DNA damage
Bibliographic record
Abstract
Artemis is a DNA repair factor required for V(D)J recombination, repair of DNA damage induced by ionizing radiation (IR) or radiomimetic drugs, and the maintenance of genome integrity. During V(D)J recombination, Artemis participates in the resolution of hairpin-sealed coding ends, a step crucial to the constitution of the gene encoding for the antigen receptor of lymphocytes. The precise role of Artemis in the repair of IR-induced DNA damage remains to be elucidated. Here we show that Artemis is constitutively phosphorylated in cultured cells and undergoes additional phosphorylation events after irradiation. The IR-induced phosphorylation is mainly, although not solely, dependent on Ataxia-telangiectasia-mutated kinase (ATM). The physiological role of these phosphorylation events remains unknown, as in vitro-generated Artemis mutants, which present impaired IR-induced phosphorylation, still display an activity sufficient to complement the V(D)J recombination defect and the increased radiosensibility of Artemis-deficient cells. Thus, Artemis is an effector of DNA repair that can be phosphorylated by ATM, and possibly by DNA-PKcs and ATR depending upon the type of DNA damage.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
