泛素化是通过三个酶促步骤实现的。在ATP依赖的过程中,泛素酶(E1)催化与泛素形成活性硫酯键,然后转移到泛素载体蛋白的活性位点半胱氨酸(E2)。泛素级联对特定底物蛋白的选择性依赖于E2结合酶(细胞中包含的相对较少)和泛素-蛋白连接酶(E3)之间的相互作用,迄今为止已经鉴定出600多种这种酶。E3s是一个大的,多样化的蛋白质组,其特征是几个确定的基序之一。这些包括HECT(与e6相关蛋白c端同源),RING(真正有趣的新基因)或U-box(没有Zn2+结合配体的完整补充的修饰的RING基序)结构域。而HECTE3s在泛素化过程中具有直接的催化作用,RING和U-boxE3s促进蛋白质泛素化。后两种E3类型充当适配器类分子。它们使E2和底物足够接近,从而促进底物的泛素化。虽然许多RING-typee3,如MDM2和c-Cbl,可以单独发挥作用,但其他一些是作为更大的多蛋白复合体的组成部分,如后期促进复合体。综上所述,这些多面的特性和相互作用使E3s能够利用泛素-蛋白酶体系统,在真核生物的所有细胞中提供一种强大而具体的蛋白质机制。该筛选了11种常用E2结合酶,可以筛选具有E3连接酶活性的蛋白所匹配的E2酶.Recombinant Canine PRLR Protein,hFc Tag
