WebJul 27, 2024 · Background HDAC9 (histone deacetylase 9) belongs to the class IIa family of histone deacetylases. This enzyme can shuttle freely between the nucleus and cytoplasm and promotes tissue-specific transcriptional regulation by interacting with histone and non-histone substrates. HDAC9 plays an essential role in diverse physiological processes … Histone deacetylases (EC 3.5.1.98, HDAC) are a class of enzymes that remove acetyl groups (O=C-CH3) from an ε-N-acetyl lysine amino acid on both histone and non-histone proteins. HDACs allow histones to wrap the DNA more tightly. This is important because DNA is wrapped around histones, and DNA … See more Together with the acetylpolyamine amidohydrolases and the acetoin utilization proteins, the histone deacetylases form an ancient protein superfamily known as the histone deacetylase … See more HDACs are conserved across evolution, showing orthologs in all eukaryotes and even in Archaea. All upper eukaryotes, including vertebrates, plants and arthropods, … See more Histone modification Histone tails are normally positively charged due to amine groups present on their lysine and arginine amino acids. These positive charges … See more Histone deacetylase inhibitors (HDIs) have a long history of use in psychiatry and neurology as mood stabilizers and anti-epileptics, for example, valproic acid. In more recent times, … See more HDAC proteins are grouped into four classes (see above) based on function and DNA sequence similarity. Class I, II and IV are considered "classical" HDACs whose activities are inhibited by trichostatin A (TSA) and have a zinc dependent active site, whereas Class … See more Within the Class I HDACs, HDAC 1, 2, and 3 are found primarily in the nucleus, whereas HDAC8 is found in both the nucleus and the cytoplasm, and is also membrane … See more Inherited mutations in the gene encoding FUS, an RNA/DNA binding protein, are causally linked to amyotrophic lateral sclerosis (ALS).
