chromatin. Many biological processes are regulated via post-translational modifications of
key proteins. Acetylation of lysine residues at the N-terminal histone tails is one of the most
studied covalent modifications influencing gene regulation in eukaryotic cells. This review
focuses on the role of enzymes involved in controlling both histone and non-histone proteins
acetylation levels in the cell, with particular emphasis on their effects on cancer.
