Abstract B13: Involvement of PAF1 complex in the DNA damage response
Bibliographic record
Abstract
Abstract PAF1 complex is a transcriptional complex composed of PAF1, CTR9, CDC73, LEO1, RTF1 and SKI8 in human. It plays a key role in the regulation of every step of transcription, from initiation to termination. PAF1 complex associates with RNA polymerase ΙΙ during transcription, and regulates modification patterns of surrounding histones or chromatin structure via recruitment of histone modifying enzymes or chromatin remodeling factors to the actively transcribed site. In yeast, PAF1 complex has been also proposed to involve in other DNA associated processes, like DNA recombination, replication, and repair. However, detailed molecular mechanism of this regulation has not been fully understood. We recently observed significant DNA breakage in the PAF1 complex depleted cells. DNA repair of artificially introduced DNA break by I-SceI endonuclease was less efficiently repaired in these cells, indicating the connection between the DNA damage repair and active transcription. The molecular mechanism of this regulation will be discussed. Citation Format: Garin Park, Nari Kim, Joo-Yeon Yoo. Involvement of PAF1 complex in the DNA damage response [abstract].

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
