Erasers of histone acetylation: the histone deacetylase enzymes.
Histone deacetylases (HDACs) are enzymes that catalyze the removal of acetyl functional groups from the lysine residues of both histone and nonhistone proteins. In humans, there are 18 HDAC enzymes that use either zinc- or NAD(+)-dependent mechanisms to deacetylate acetyl lysine substrates. Although removal of histone acetyl epigenetic modification by HDACs regulates chromatin structure and tra...
متن کاملFunctional interplay between cylindromatosis and histone deacetylase 6 in ciliary homeostasis revealed by phenotypic analysis of double knockout mice
Cilia are present in most vertebrate tissues with a wide variety of functions, and abnormalities of cilia are linked to numerous human disorders. However, the molecular events underlying ciliary homeostasis are poorly understood. In this study, we generated double knockout (DKO) mice for the deubiquitinase cylindromatosis (CYLD) and histone deacetylase 6 (HDAC6), two critical ciliary regulators...
متن کاملFunctional significance of histone deacetylase diversity.
Nucleocytoplasmic shuttling of histone deacetylases is emerging as a major step in determining the composition, and hence the activity, of the corresponding nuclear regulatory complexes. This shuttling process is one of the distinctive characteristics of these enzymes, themselves belonging to structurally and functionally different classes. Considering the specific features of each class of dea...
متن کاملFunctional domains of histone deacetylase-3.
Post-translational modifications of histones, in general, and acetylation/deacetylation, in particular, can dramatically alter gene expression in eukaryotic cells. In humans, four highly homologous class I HDAC enzymes (HDAC1, HDAC2, HDAC3, and HDAC8) have been identified to date. Although HDAC3 shares some structural and functional similarities with other class I HDACs, it exists in multisubun...
متن کاملHistone Demethylase Inhibition
N-Methylation of histone lysine residues is an “epigenetic modification” that can be either transcriptionally activating or deactivating, depending on the position of the lysine, its methylation state and the presence of other modifications. The largest family of demethylases, the JmjC enzymes, employ 2-oxoglutarate (2OG) as a cosubstrate (Figure 1a). Some JmjC demethylases are targeted for can...
