The process of SUMO conjugation to target proteins is similar to the molecular chain of events observed with ubiquitin (1). SUMO is conjugated to target proteins through the coordinated action of the cellular SUMO conjugation machinery, which consists of the E1, E2, and E3 enzymes (2). The canonical SUMO E1 activating enzyme is a heterodimer consisting of Ubiquitin-like 1-activating enzyme E1A (UBLE1A, SAE1) and UBLE1B (SAE2, UBA2) subunits. Mature SUMO is activated by E1 in an ATP-dependent reaction that generates adenylated SUMO, which functions as a high-energy intermediate in the formation of a thioester linkage between SUMO and Cys173 of SAE2 (3,4). SUMO is subsequently transferred from SAE2 to the SUMO E2 conjugating enzyme UBE2I (5). Research studies indicate that UBLE1A (SAE1) is a nuclear protein and c-Myc transcriptional target whose expression is required for Myc-driven tumorigenesis (6-8).

SUMO修饰结合于目标蛋白质的过程是类似于泛素化修饰的事件(1)。SUMO是通过由E1,E2和E3酶(2)组成的SUMO修饰系统协同作用并偶联于目标蛋白质。典型的SUMOE1激活酶是由UBLE1A(SAE1) 和UBLE1B (SAE2, UBA2)亚基组成的异源二聚体。成熟SUMO是由激活酶E1通过依赖于ATP的反应,生成腺苷酸化SUMO(SUMO与UBA2的Cys173之间形成硫酯键而形成的一种高能中间体)(3,4)。SUMO然后从UBA2转移到SUMO的E2共价连接酶UBE2I(5)。最近的证据表明,UBLE1A (SAE1)是一种核蛋白,并且是c-Myc的转录靶基因,它的表达是myc导致的肿瘤发生所必需的(6-8)。
