Description

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 and HDAC3 belong to Class I HDACs and HDAC4, HDAC6, and HDAC7 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.

Mammalian histone deacetylases (HDACs) are classified into three classes according to sequence homology. HDAC1, HDAC2, HDAC3 and HDAC8 belong to class I HDACs and HDAC4, HDAC6, and HDAC7 belong to class II HDACs. Class III consists of the yeast sirtuins (sir2-like protein). Class I HDACs are ubiquitously expressed. Whereas, most of the class II HDACs show tissue-specific expression. The antibody is affinity-purified using the immunizing peptide immobilized on agarose.

Biochem/physiol Actions

Histone deacetylase 4 (HDAC4) contains import and export nuclear signal that aids in nucleocytoplasmic shuttling. It has physical and functional interactions with transcription factor myocyte enhancer factor-2 (Mef2) protein and 14-3-3. This interaction disturbs nucleocytoplasmic shuttling and then guides HDAC4 to the cytoplasm and the nucleus, respectively. In addition, HDAC4 with HDAC5 and HDAC7 represses transcription by binding to the nuclear receptor co-repressors silencing mediator of retinoic acid and thyroid hormone receptors (SMRT) and nuclear receptor co-repressor (NCOR).

Studies show that HDAC4 contains a composed import and export nuclear signal that aids in nucleocytoplasmic shuttling. It has physical and functional interactions with transcription factor MEF2C and 14-3-3. This interaction results in the shuttling and it guides HDAC4 to the cytoplasm and the nucleus.The C-terminal domain of HDAC4 shows innate histone deacetylase activity. It is seen that MEF2C combines with HDAC4 at the N-terminal domain and downmodulate c-jun promoter activity.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 1% bovine serum albumin and 15 mM sodium azide.

Storage and Stability

For continuous use, store at 2-8°C for up to one month. For prolonged storage, freeze in working aliquots at -20°C. Repeated freezing and thawing is not recommended. Storage in frost-free freezers is also not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use. Working dilutions should be discarded if not used within 12 hours.
