General description

Histone deacetylases (HDACs) are competing enzymes, belonging to histone deacetylase family. There are two classes of HDACs with six to seven different types of HDACs proteins. HDAC1,HDAC2, HDAC3, and HDAC8 belong to Class I HDACs and HDAC4, HDAC6, HDAC7, HDAC9, and HDAC10 belong to Class II HDACs. Class I HDACs consists of a single deacetylase domain at the N-termini and diversified C-terminal regions, while Class II contains a deacetylase domain at C-terminal position. Studies show that HDAC8 is a sex-linked gene located on the chromosome at position Xq21.2 - q21.3. HDAC8 gene has a molecular weight of 43kDa and it encodes a 377 amino acid protein. It is present within the nucleas. HDAC8 mRNA is seen in heart, lung, kidney, and pancreas.
The antibody is affinity-purified using the immunizing peptide immobilized on agarose.

Immunogen

synthetic peptide corresponding to amino acid residues 352-370 of human HDAC8, conjugated to KLH. The corresponding sequence in mouse differs by one amino acid.

Application

Anti-Histone Deacetylase 8 (HDAC8) antibody produced in rabbit has been used in western blotting, immunohistofluorescence and immunoblotting.

Biochem/physiol Actions

Histone deacetylation results in transcription repression leading to the formation of tight nucleosomal structure which prevents DNA accessing. {5} HDAC8 controls HDAC activity on H4 histone peptide substrates. HDAC8 is similar to the HDAC class I enzymes. In vitro expression and activity of HDAC8 was examined using FLAG tagged- HDAC8 and HDAC1. These were transfected into HeLa cells and Sf9 insect cells. After the immunoprecipitation of cell lysates the expression results were confirmend using Western blotting. Studies show that HDAC8 may play a role in role in transcriptional regulation and could possibly be regulated in a temporal or compartment-specific manner.

Physical form

Histone acetylation alters chromatin state by modifying lysines on histone and plays an important role in modulating gene transcription. A dynamic balance of histone acetylation/deacetylation is maintained by histone acetyltransferases and histone deacetylases. Emerging evidence suggests that a family of
