Histone Deacetylase 8/HDAC8 Proteins and Enzymes

Human Histone Deacetylase 8 (HDAC8) is a member of the class I histone Deacetylases (HDACs). Expression of HDAC8 is restricted to cells showing smooth muscle differentiation in normal human tissue and is a novel marker of smooth muscle differentiation. Like other class I and II HDAC members, the activity of HDAC8 is sensitive to HDAC inhibitor trichostatin A.

Sirtuin 2, is a member of the class III histone deacetylases (HDACs) and has been implicated in many cellular processes that include histone deacetylation, gene silencing, chromosomal stability, and aging (3 - 4). The enzymatic activity of class III HDACs is nicotinamide adenine dinucleotide (NAD) dependent and insensitive to HDAC inhibitor trichostatin A
