多亞基復合物催化的組蛋白乙酰化和脫乙酰化在調節真核基因表達中起關鍵作用。 該基因編碼的蛋白質屬于組蛋白脫乙酰基酶/ acuc / apha家族，是組蛋白脫乙酰基酶復合物的組成部分。 它還與視網膜母細胞瘤腫瘤抑制蛋白相互作用，這種復合物是控制細胞增殖和分化的關鍵因素。 它與轉移相關蛋白2一起使p53脫乙酰化，并調節其對細胞生長和凋亡的影響。 [由RefSeq提供，2008年7月]
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]
