背景信息

Histone deacetylase 3 (HDAC3) is a member of the histone deacetylase family, which plays a critical role in epigenetic regulation by removing acetyl groups from lysine residues on histone proteins. This enzymatic activity modulates chromatin structure and gene expression, influencing cellular processes such as proliferation, differentiation, and apoptosis. HDAC3 is classified under the Class I HDACs, alongside HDAC1. HDAC2. and HDAC8. and is ubiquitously expressed in mammalian tissues. It operates primarily within the nucleus, often in association with multiprotein complexes like the nuclear receptor corepressor (NCOR) and silencing mediator for retinoid and thyroid hormone receptors (SMRT) complexes, which target it to specific genomic loci.

Structurally, HDAC3 contains a conserved catalytic domain responsible for its deacetylase activity and an N-terminal domain that mediates interactions with corepressor proteins. Unlike some HDACs, HDAC3 requires binding to inositol tetraphosphate (IP4) or similar molecules for enzymatic activation, a unique feature critical for its biological function. Recombinant HDAC3 proteins are produced using expression systems (e.g., E. coli, insect, or mammalian cells) to study its biochemical properties, substrate specificity, and regulatory mechanisms. These engineered proteins enable in vitro assays to screen HDAC3-specific inhibitors, which are of therapeutic interest in cancer, neurodegenerative diseases, and metabolic disorders.

Research on recombinant HDAC3 has advanced understanding of its role in diseases. Dysregulation of HDAC3 is linked to tumor progression, inflammation, and circadian rhythm disruptions. Its selective inhibition has shown potential in restoring normal gene expression patterns in pathological conditions. Additionally, studies using recombinant HDAC3 have elucidated its non-histone targets, including transcription factors and cytoskeletal proteins, expanding its functional scope beyond epigenetic regulation. This highlights HDAC3 as a multifaceted enzyme with broad therapeutic and research applications.
