Abstract
Lysine acetylation refers to transfer of the acetyl moiety from acetyl-CoA to the ε-amino group of a lysine residue on a protein. This has recently emerged as a major covalent modification and interplays with other modifications, such as phosphorylation, methylation, ubiquitination (addition of a small protein called ubiquitin) and SUMOylation [addition of a ubiquitin-like protein known as SUMO (small ubiquitin-related modifier)], to form multisite modification programmes for cellular regulation in diverse organisms. This modification is post-translational (i.e. after synthesis of a protein) and reversible, with its level being dynamically balanced by two groups of enzymes known as lysine acetyltransferases and deacetylases. The acetyltransferases belong to three major families, whereas deacetylases have been divided into the classical and sirtuin [Sir-tu-in, for Sir2 (silent information regulator 2)-like protein; named after the yeast protein Sir2] families. In addition to these enzymes, proteins containing the bromodomain, a protein module named after the fly protein Brahma (God of creation in Hindu), are relevant to lysine acetylation biology due to their ability to recognize acetyl-lysine-containing peptides. Importantly, recent studies have made intimate links between these three different groups of proteins to different pathological conditions. In this chapter, we provide a brief overview of these proteins and emphasize their direct links to related human diseases.

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
