Histone Deacetylase 8/HDAC8 Antibody

HDAC8 (Histone deacetylase 8) is a 50 kDa member of the class I subfamily, histone deacetylase family of transcriptional regulators. It is a smooth muscle enzyme that deacetylates histone lysines, blocking gene transcription. HDAC8 appears to function as a monomer, and phosphorylation at Ser39 inhibits activity. Human HDAC8 is 377 amino acids (aa) in length. It contains a series of  alpha helices and  strands, plus a catalytic ferrous ion binding site (Asp178-His180-Asp267). There are four potential splice variants, all of which possess an alternate start site 38 aa upstream of the standard start site. Three have additional changes; two show a one and three aa substitution respectively for aa 211-377, while a third has a 15 aa substitution for aa 148-377. Human HDAC8 shares more than 96% aa identity with both mouse and canine HDAC8.
