Abstract
To paraphrase Robert Burns's poem To a Mouse, the best laid schemes of DNA-protein complex purification often go awry. Chromatin with its heterogeneous and dynamic protein composition remains difficult to analyze. Still critical progress has been made in recent years in characterizing the interface between DNA and proteins due, in part, to significant advances in proteomic technologies. Proteomics has progressed to a point where affinity purification of soluble complexes and protein identification by mass spectrometry are routine. The new challenge for chromatin proteomics lies in studying proteins and protein complexes in their native environment, which is on chromatin. These novel types of data represent an additional layer of information that can be used to better characterize and understand cellular processes. This review will focus on the past contributions as well as on emerging mass spectrometry-based methodologies attempting to better define the complex relationship between proteins, protein complexes and DNA.

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
