Histone hat
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 … Visa mer HATs are traditionally divided into two different classes based on their subcellular localization. Type A HATs are located in the nucleus and are involved in the regulation of gene expression through acetylation of nucleosomal histones Visa mer The basic mechanism catalyzed by HATs involves the transfer of an acetyl group from acetyl-CoA to the ε-amino group of a target lysine side-chain within a histone. Different families of HATs employ unique strategies in order to effect such a transformation. Visa mer The catalytic activity of HATs is regulated by two types of mechanisms: (1) interaction with regulatory protein subunits and (2) autoacetylation. A given HAT may be regulated in multiple ways, and the same effector may actually lead to different outcomes … Visa mer In general, HATs are characterized by a structurally conserved core region made up of a three-stranded β-sheet followed by a long α-helix parallel to and spanning one side of it. The core region, which corresponds to motifs A, B, and D of the GNAT proteins, is … Visa mer The structures of several HAT domains bound to acetyl-CoA and histone substrate peptides reveal that the latter bind across a groove on the protein that is formed by the central core … Visa mer Histone acetyltransferases (HATs) and histone deacetylases (HDACs) are recruited to their target promoters through physical interactions … Visa mer Chromatin remodeling Histone acetyltransferases serve many biological roles inside the cell. Chromatin is a combination of proteins and DNA found in the Visa mer WebbHistone acetyltransferases (HATs) have critical roles in cellular functions and are involved in the regulation of gene transcription, differentiation, and proliferation.

HDACs catalytically reverse this process. LPS-stimulated macrophages show increased histone H4 acetylation (H4Ac), an indicator of open chromatin at numerous sites across the genome.
