    • This invention discloses the first cellular acetylated substrate protein of SIRT3, Acetyl-CoA synthetase 2 (AceCS2), which is a mitochondrial matrix protein. AceCS2 is reversibly acetylated at lysine 642 (Lys642) in the active site of the enzyme. The mitochondrial sirtuin SIRT3 interacts with AceCS2 and deacetylates Lys642 both in vitro and in vivo. Deacetylation of AceCS2 by SIRT3 activates the acetyl-CoA synthetase activity of AceCS2. Thus, a mammalian sirtuin directly controls the activity of a metabolic enzyme via reversible lysine acetylation. Modulators of the acetylation status or the activity of AceCS2 are useful for the treatment of pathological conditions, such as type II diabetes, hypercholesterolemia, hyperlipidemia, and obesity.
    • 本发明公开了作为线粒体基质蛋白质的SIRT3的第一细胞乙酰化底物蛋白,乙酰辅酶A合成酶2(AceCS2)。 AceCS2在酶的活性位点的赖氨酸642(Lys642)处可逆地乙酰化。 线粒体sirtuin SIRT3在体外和体内都与AceCS2和脱乙酰基Lys642相互作用。 通过SIRT3对AceCS2的脱乙酰化激活了AceCS2的乙酰辅酶A合成酶活性。 因此,哺乳动物沉默调节蛋白通过可逆赖氨酸乙酰化直接控制代谢酶的活性。 乙酰化状态或AceCS2活性的调节剂可用于治疗病理状况,如II型糖尿病,高胆固醇血症,高脂血症和肥胖症。

    • The present invention provides treatment methods involving modulating a sirtuin activity and/or a sirtuin mRNA and/or a sirtuin polypeptide level. In some embodiments, the present invention provides treatment methods involving modulating SIRT1 activity and/or SIRT mRNA and/or polypeptide level. The present invention provides methods of inhibiting SIRT1 Tat deacetylase activity. Methods of inhibiting SIRT1 Tat deacetylase activity are useful for treating immunodeficiency virus infections, particularly human immunodeficiency virus (HIV) infection. Thus, the present invention provides methods of treating an immunodeficiency virus infection, generally involving inhibiting SIRT1 Tat deacetylase activity. The present invention further provides methods of identifying agents that modulate sirtuin activity (e.g., SIRT1 activity), particularly ability of sirtuins to interact with (e.g., bind and/or deacetylate) a substrate, e.g., a viral substrate such as a Tat polypeptide. The present invention further provides active agents that modulate sirtuin activity or expression; and compositions, including pharmaceutical compositions, comprising the active agents.
    • 本发明提供了涉及调节沉默调节蛋白的活性和/或sirtuin mRNA和/或sirtuin多肽水平的治疗方法。 在一些实施方案中,本发明提供了涉及调节SIRT1活性和/或SIRT mRNA和/或多肽水平的治疗方法。 本发明提供抑制SIRT1 Tat脱乙酰酶活性的方法。 抑制SIRT1 Tat脱乙酰酶活性的方法可用于治疗免疫缺陷病毒感染,特别是人类免疫缺陷病毒(HIV)感染。 因此,本发明提供了治疗免疫缺陷病毒感染的方法,通常涉及抑制SIRT1 Tat脱乙酰酶的活性。 本发明进一步提供了鉴定调节沉默调节蛋白的活性(例如,SIRT1活性)的药剂的方法,特别是sirtuins与底物(例如,结合和/或脱乙酰化)例如病毒底物如Tat多肽的能力。 本发明还提供调节沉默调节蛋白的活性或表达的活性剂; 和包含活性剂的组合物,包括药物组合物。
