Histone body
WebbCanonical histone gene transcription and RNA processing occur in nuclear subdomains called Histone Locus Bodies (HLB) that contain the clustered histone genes, … WebbHistone Acetylation and Acetyltransferases Lysine acetylation is a reaction in which an acetyl group from the acetyl- coenzyme A (acetylCoA) cofactor is transferred to the -amino nitrogen of e lysine residues. This reaction is catalyzed by histone acetyltransferases (HATs), whereas the reverse reaction is performed by histone deacetylases (HDACs).

WebbAcetylation of all histone residues are activating, and H3K4 is no exception. The real interest in H3K4 lies in its methylation. Methylation of this fourth amino acid residue from the N-terminus of histone H3 is one of the most studied histone modifications, and with good reason: it’s tightly associated with the promoters of active genes. Webb4-Hexylresorcinol (4HR) has been used as a food additive, however, it has been recently demonstrated as a Class I histone deacetylase inhibitor (HDACi). Unlike other HDACi, …

WebbHistone production is very tightly coupled to DNA synthesis and is rapidly shut off when replication finishes or is halted by treatment with mutagenic agents. Histone regu‐ lation is very important and accumulation of free histones in the cell has been shown to be highly deleterious for the cell and lead to chromosome loss [2].
