The Histone Variant H2A.Z C-Terminal Domain Has Locus-Specific Differential Effects on H2A.Z Occupancy and Nucleosome Localization
Bibliographic record
Abstract
C-terminal region of histone variant H2A.Z can mediate its special function in performing gene regulation by interacting with effector proteins and chaperones. These functional interactions allow H2A.Z not only to incorporate to very specific gene regulatory regions, but also to facilitate the gene expression process. To achieve this, we used a chimeric protein which lacks the native H2A.Z C-terminal region but contains an acidic activating region, a module that is known to interact with components of chromatin-remodeling entities and/or transcription modulators. We reasoned that because this activating region can fulfill the role of the H2A.Z C-terminal region, at least in part, the role of the latter would be to interact with these activating region targets.

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.
