Figure 1. Mechanisms of action of acetylation.
A. KATs target both tails and globular domains of all 4 histone proteins. B. KATs acetylate non-histone proteins including transcription factors (TF) as well as metabolic enzymes and other nuclear and cytoplasmic proteins. C. Bromodomain-containing proteins bind to acetyl-lysines on histone tails and on non-histone proteins.
