|Function||Responsible for the deacetylation of lysine residues on the N-terminal part of the core histones (H2A, H2B, H3 and H4), and some other non-histone substrates. Histone deacetylation gives a tag for epigenetic repression and plays an important role in transcriptional regulation, cell cycle progression and developmental events. Histone deacetylases act via the formation of large multiprotein complexes. Participates in the BCL6 transcriptional repressor activity by deacetylating the H3 'Lys- 27' (H3K27) on enhancer elements, antagonizing EP300 acetyltransferase activity and repressing proximal gene expression. Probably participates in the regulation of transcription through its binding to the zinc-finger transcription factor YY1; increases YY1 repression activity. Required to repress transcription of the POU1F1 transcription factor. Acts as a molecular chaperone for shuttling phosphorylated NR2C1 to PML bodies for sumoylation (PubMed:21444723, PubMed:23911289). Contributes, together with XBP1 isoform 1, to the activation of NFE2L2-mediated HMOX1 transcription factor gene expression in a PI(3)K/mTORC2/Akt-dependent signaling pathway leading to endothelial cell (EC) survival under disturbed flow/oxidative stress (PubMed:25190803).|
|Cellular Location||Nucleus. Cytoplasm. Cytoplasm, cytosol. Note=Colocalizes with XBP1 and AKT1 in the cytoplasm (PubMed:25190803). Predominantly expressed in the nucleus in the presence of CCAR2.|
|Tissue Location||Widely expressed.|

Histones play a critical role in transcriptionalregulation, cell cycle progression, and developmental events.Histone acetylation/deacetylation alters chromosome structure andaffects transcription factor access to DNA. The protein encoded bythis gene belongs to the histone deacetylase/acuc/apha family. Ithas histone deacetylase activity and represses transcription whentethered to a promoter. It may participate in the regulation oftranscription through its binding with the zinc-fingertranscription factor YY1. This protein can also down-regulate p53function and thus modulate cell growth and apoptosis. This gene isregarded as a potential tumor suppressor gene. [provided byRefSeq].
