组蛋白翻译后修饰是重要的表观遗传调控方式,包括组蛋白甲基化、乙酰化、磷酸化和泛素化等,在真核生物的基因组DNA复制、损伤修复、基因转录等生物学过程中发挥着重要的作用.组蛋白H2A单泛素化修饰(H2Aub)在动植物中高度保守,通常与基因的转录抑制相关[1,2].组蛋白泛素化是可逆的,维持生物体内组蛋白泛素化的正常水平对正常生长发育至关重要.以往的研究表明,动植物中具有保守RING结构域的E3连接酶形成PRC1复合体,负责催化H2A的单泛素修饰[1,3].组蛋白H2A去泛素化需要去泛素蛋白酶催化,对调控染色质上的H2A泛素修饰水平具有重要作用.以往的研究已经在动物中弄清了H2A去泛素化的分子机制,然而对植物中组蛋白H2A去泛素化的分子机制知之甚少.
