Histone acetylation and deacetylation, catalyzed by multisubunit complexes, play a key role in the regulation of eukaryotic gene expression. The protein encoded by this gene belongs to the histone deacetylase/acuc/apha family and is a component of the histone deacetylase complex. It also interacts with retinoblastoma tumor-suppressor protein and this complex is a key element in the control of cell proliferation and differentiation. Together with metastasis-associated protein-2, it deacetylates p53 and modulates its effect on cell growth and apoptosis. [provided by RefSeq, Jul 2008]
Forensic Context
A study in mouse cardiac mesenchymal stem cells demonstrated that overexpression of the HDAC1 activated cell cycle pathways, promoted proliferation, and induced transcriptional reprogramming, as evidenced by increased pHH3 protein levels and the upregulation of genes including SELP, TUBB6, ACTA2, AURKB, PCNA, and multiple identified hub genes [Zhang et al. DOI:10.3390/biom15050662].
