Abstract
CpG islands (CGIs) are regions enriched in the dinucleotide CpG; they constitute the promoter of about 60% of mammalian genes. In cancer cells, some promoter-associated CGIs become heavily methylated on cytosines, and the corresponding genes undergo stable transcriptional silencing. Hypermethylated CGIs attract methyl-CpG-binding proteins (MBPs), which have been shown to recruit chromatin modifiers and cause transcriptional repression. These observations have led to the prevalent model that methyl-CpG-binding proteins are promoter-proximal transcriptional repressors. Recent discoveries challenge this idea and raise a number of questions. Here we discuss the following issues: what are other possible roles for the known MBPs? Why are these proteins not essential in mammals? Are there other MBPs left to discover? Could CpG methylation be nonessential?

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
