组蛋白H3赖氨酸56乙酰化(H3K56Ac)最近已被鉴定并且显示对于酵母中的基因组稳定性是重要的。然而,H3K56乙酰化是否发生在哺乳动物中尚不清楚。在此,我们报告H3K56Ac存在于哺乳动物中。哺乳动物H3K56Ac需要组蛋白伴侣Asf1,主要发生在未应激细胞的S期。此外,SIRT1是NAD+依赖性脱乙酰酶的sirtuin家族的哺乳动物成员,调节H3K56的脱乙酰化。我们进一步表明,适当的H3K56乙酰化对基因组稳定性和DNA损伤反应至关重要。这些结果确立了H3K56Ac在哺乳动物中的存在和功能意义,并鉴定了这种修饰的两个调节剂。
Histone H3 lysine 56 acetylation (H3K56Ac) has recently been identified and shown to be important for genomic stability in yeast. However, whether or not H3K56 acetylation occurs in mammals is not clear. Here, we report that H3K56Ac exists in mammals. Mammalian H3K56Ac requires the histone chaperone Asf1 and occurs mainly at the S phase in unstressed cells. Moreover, SIRT1, which is a mammalian member of sirtuin family of NAD+-dependent deacetylases, regulates the deacetylation of H3K56. We further showed that proper H3K56 acetylation is critical for genomic stability and DNA damage response. These results establish the existence and functional significance of H3K56Ac in mammals and identify two regulators of this modification.
