WebHistone acetylation, or the addition of an acetyl group to histones, is facilitated by histone acetyltransferases (HATs) which target lysine (K) residues on the N-terminal histone tail. Histone deacetylases (HDACs) facilitate the removal of such groups. The positive charge on a histone is always neutralized upon acetylation, creating euchromatin which increases … WebJun 3, 2024 · Cancer is a major global health challenge for our health system, despite the important pharmacological and therapeutic discoveries we have seen since past 5 decades.
