Histone Acetyltransferase
Histone acetyltransferases (HATs) are enzymes that acetylate conserved lysine amino acids on histone proteins by transferring an acetyl group from acetyl CoA to form ε-N-acetyllysine. DNA is wrapped around histones, and, by transferring an acetyl group to the histones, genes can be turned on and off. In general, histone acetylation increases gene expression. HATs are traditionally divided into two different classes based on their subcellular localization. Three important nuclear receptor coactivators that display HAT activity are SRC-1, ACTR, and TIF-2.
