Abstract
The SWI/SNF family of chromatin remodelling complexes, comprising BAF, PBAF and ncBAF, is known for their critical roles in regulating chromatin accessibility and gene expression in mammalian cells. Recent advances have shed light on a function for SWI/SNF complexes, particularly PBAF, at centromeres. In this review, we explore the emerging roles of SWI/SNF complexes in safeguarding centromere stability and discuss how disruption of PBAF leads to centromere fragility. We propose that PBAF contributes to the establishment and maintenance of boundaries between heterochromatin and euchromatin regions within centromeres and pericentromeres, thus contributing to their overall architecture. By preserving these boundaries, PBAF ensures the functional integrity of centromeres, which is essential for faithful chromosome segregation.

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
