Function
HDAC3 (histone deacetylase 3) is a class I histone deacetylase that functions as a central epigenetic regulator of chromatin structure and transcriptional repression through its association with nuclear receptor corepressor complexes containing NCOR and SMRT[1][2]. Mechanistically, HDAC3 forms an enzymatically active complex with NCOR/SMRT and associated cofactors, enabling histone deacetylation and coordinated control of gene expression programs involved in metabolism, circadian regulation, and cellular homeostasis[2][3][4]. HDAC3 also participates in signal-responsive transcriptional regulation, including repression of the JNK pathway and modulation of inflammatory gene expression, linking epigenetic regulation to cellular stress and immune responses[5][6]. In disease models, dysregulation of HDAC3-dependent transcriptional networks has been associated with metabolic disorders, cardiovascular pathology, inflammatory diseases, and cancer-related transcriptional abnormalities[4][6]. HDAC3 is additionally required for normal embryonic development, organ function, and maintenance of metabolic processes, highlighting its broad physiological significance[4]. Compared with related class I HDAC isoforms, HDAC3 is distinguished by its obligate functional interaction with the NCOR/SMRT corepressor complex and its dependence on corepressor-mediated activation for full biological activity[1][2][7]. Structural and genetic studies further demonstrate that disruption of HDAC3-corepressor interactions compromises HDAC3 function in vivo, emphasizing a unique regulatory mechanism not shared to the same extent by other HDAC family members[7][3]. For experimental applications, selective HDAC3 inhibitors are widely used to investigate epigenetic control of inflammation, metabolism, and disease-associated transcriptional programs, while offering greater isoform specificity than pan-HDAC inhibition strategies[6][4].
