Abstract
The incorporation of variant histone H2A.Z within chromatin is important for proper gene expression and genome stability. H2A.Z is inserted at discrete loci by the Swr1 or Swr1-like remodeling complexes, although very little is known about the nature of the targeting mechanism involved. Replacement of canonical histone H2A for H2A.Z has been shown to modify nucleosome dynamics, although discrepancies still exist in the literature regarding the mechanisms. Recent experiments have shown that H2A.Z can allow nucleosomes to adopt stable translational positions as compared to H2A, which could influence the accessibility to DNA regulatory proteins. This review provides a brief overview of H2A.Z biology and presents hypotheses that could reconcile contradictory reports that are found in the literature regarding the influence of H2A.Z on nucleosome stability.

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
