Abstract
Background The NuA4 histone acetyltransferase is a highly conserved multisubunit complex responsible for acetylation of nucleosomal histone H4 and H2A. Mutations in different NuA4 subunits create cell cycle arrest or delay in G2/M. The NuA4 complex is important for gene expression but also the efficient repair of DNA double strand breaks (DSBs) in vivo. NuA4 is rapidly recruited to chromatin surrounding a DSB in vivo at the same time histone H2A (X) is phosphorylated in the neighboring region (g-H2AX). While we have shown that NuA4 can interact with phosphorylated H2A(X), we speculated that another interaction was required for the initial recruitment of NuA4 at the break. Based on the presence of an ATM-related factor within NuA4, the subunitTra1 (TRRAP), it was tempting to postulate that DSB sensing factors known to recruit ATM family PIKK factors could be responsible for NuA4 recruitment.

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 it
