Regulatory ubiquitylation during the response to DNA double‐strand breaks
Bibliographic record
Abstract
The chromatin‐based response to DNA double‐strand breaks (DSBs) is characterized by the accumulation of DNA repair factors and DNA damage signaling molecules within a large domain that surrounds the lesion. This response is largely dependent on ATM‐dependent phosphorylation but also on chromatin ubiquitylation. Indeed, the RNF8 and RNF168 E3 ubiquitin ligases are necessary for the accumulation of proteins such as 53BP1, BRCA1 and RAD18 at sites of DNA damage. The critical importance of this pathway is manifested by the observation that biallelic mutations in the RNF168 gene results in an ataxia‐telangiectasia‐like syndrome referred to as RIDDLE. We are interested in understanding how this pathway is regulated and how ubiquitin‐dependent protein interactions orchestrate the hierarchy of protein recruitment at sites of DNA lesions. I will present our current understanding on the regulation and organization of this signaling cascade and in particular, I will focus my presentation on addressing how 53BP1 is recruited at site of DNA damage, in a ubiquitin‐dependent manner.

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.
