UHRF1 Links the Histone Code and DNA Methylation to Ensure Faithful Epigenetic Memory Inheritance
Bibliographic record
Abstract
Epigenetics is the study of the transmission of cell memory through mitosis or meiosis that is not based on the DNA sequence. At the molecular level the epigenetic memory of a cell is embedded in DNA methylation, histone post-translational modifications, RNA interference and histone isoform variation. There is a tight link between histone post-translational modifications (the histone code) and DNA methylation, as modifications of histones contribute to the establishment of DNA methylation patterns and vice versa. Interestingly, proteins have recently been identified that can simultaneously read both methylated DNA and the histone code. UHRF1 ful-fills these requirements by having unique structural domains that allow concurrent recognition of histone modifications and methylated DNA. Herein, we review our current knowledge of UHRF1 and discuss how this protein ensures the link between histone marks and DNA methylation. Understanding the molecular functions of this protein may reveal the physiological relevance of the linkage between these layers of epigenetic marks.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
