WebbArun Kumar. Tags: Epigenetics. Eukaryotic DNA is packaged and wrapped around proteins known as histones which protect and regulate gene expression. The structure of DNA wrapped around histone octamers is known as chromatin. Chromatin at the first level of its organization appears as a linear array of uniform structural units, nucleosomes. Webb22 aug. 2024 · Histone deacetylases (HDACs) are important cellular regulators of chromatin structure and gene expression. HDACs can function as enzymes that remove acetyl groups from acetyl-lysines of histones. Through this activity, HDACs can either repress or activate gene expression [ 1 – 4 ].
