Histone deacetylase 8 (HDAC8) is a member of the class I HDAC family, which plays a critical role in epigenetic regulation by removing acetyl groups from lysine residues on histones and non-histone proteins. This zinc-dependent enzyme is encoded by the *HDAC8* gene located on the X chromosome. Unlike other class I HDACs (HDAC1-3), HDAC8 exhibits distinct structural flexibility and substrate specificity, making it a unique target for biochemical and therapeutic studies. It regulates chromatin remodeling, gene expression, and cellular processes such as mitosis, DNA repair, and metabolism. Dysregulation of HDAC8 is implicated in cancers, neurodevelopmental disorders, and Cornelia de Lange syndrome, where mutations in HDAC8 disrupt cohesin complex dynamics.
Recombinant HDAC8 protein is produced via heterologous expression systems (e.g., *E. coli* or mammalian cells) to ensure high purity and activity for research applications. Its production typically involves affinity chromatography followed by enzymatic validation. The recombinant form enables detailed structural studies (e.g., X-ray crystallography) and functional assays to explore catalytic mechanisms and inhibitor interactions. HDAC8’s substrate versatility, including its ability to deacetylate non-histone targets like estrogen receptor alpha and p53. underscores its broader regulatory roles.
Pharmaceutically, HDAC8-selective inhibitors are under investigation for cancer therapy and rare genetic disorders. Research on recombinant HDAC8 advances understanding of epigenetic regulation and supports drug discovery, offering insights into isoform-specific HDAC functions. Its study bridges molecular biology and translational medicine, highlighting its significance in both basic science and clinical applications.
