The sirtuin family are all classified as class III HDACs. HDACs catalyze acetyl group removal from lysine residues in histones and non-histone proteins, causing transcriptional repression.
WebAbstract The acetylation level of histones on lysine residues regulated by histone acetyltransferases and histone deacetylases plays an important but under-studied role in the control of gene expression in plants. WebHistone deacetylases can be regulated by endogenous factors, dietary components, synthetic inhibitors and bacteria-derived signals. Studies in mice with a specific deletion of HDAC3 in intestinal epithelial cells (IECs) show a deregulated IEC's gene expression.

Introduction. Histone acetylation is a specific type of chromatin modification that serves as a key regulatory mechanism for many cellular processes including DNA replication and regulation of gene expression [1–6].The steady state of histone acetylation is determined by the antagonistic activities of histone …
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, HDIs are being studied as a mitigator or treatment for neurodegenerative diseases. Also in recent years, there has been … See more 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 … 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 … See more Inherited mutations in the gene encoding FUS, an RNA/DNA binding protein, are causally linked to amyotrophic lateral sclerosis (ALS).
