背景信息

Histone deacetylase 1 (HDAC1) is a conserved epigenetic regulator belonging to the class I HDAC family, which plays a critical role in chromatin remodeling and gene expression control. It catalyzes the removal of acetyl groups from lysine residues on histones, leading to chromatin condensation and transcriptional repression. Beyond histones, HDAC1 also deacetylates non-histone proteins, influencing processes like DNA repair, cell cycle progression, and apoptosis. Dysregulation of HDAC1 activity is implicated in cancer, neurodegenerative diseases, and inflammatory disorders, making it a key therapeutic target.

Recombinant HDAC1 protein is produced through heterologous expression systems (e.g., E. coli, insect, or mammalian cells) to enable biochemical and functional studies. The recombinant form typically retains the conserved catalytic domain (zinc-dependent deacetylase activity) and regulatory regions required for interactions with co-factors like Sin3. NuRD, or CoREST complexes. Purification tags (e.g., GST, His-tag) are often added to facilitate isolation. Post-translational modifications (phosphorylation, ubiquitination) observed in native HDAC1 may be absent depending on the expression system, potentially affecting functional analyses.

Researchers utilize recombinant HDAC1 to study enzyme kinetics, screen inhibitors for drug development, and investigate its role in chromatin dynamics. Structural studies using recombinant protein have revealed insights into substrate binding and catalytic mechanisms. Mutant variants (e.g., catalytic site mutants) serve as controls in activity assays. Its application extends to disease models, where HDAC1 overexpression or knockdown helps elucidate pathological mechanisms. As HDAC inhibitors gain clinical traction (e.g., cancer therapeutics), recombinant HDAC1 remains essential for characterizing compound specificity and optimizing targeted therapies.
