Sirtuins are NAD-dependent deacetylases that are conserved from yeast to mammals. A new report sheds light on the function of SIRT7, the least understood member of the Sirtuin family by identifying its locus-specific H3K18 deacetylase activity, and linking it to maintenance of cellular transformation in malignancies.
Sirtuins 是一种依赖 NAD 的去乙酰化酶,从酵母到哺乳动物都有保守。一项新的研究报告阐明了 Sirtuin 家族中了解最少的成员 SIRT7 的功能,该研究通过鉴定其特定位点的 H3K18 去乙酰化酶活性,并将其与恶性肿瘤中细胞转化的维持联系起来。
