基于活性的双泛素探针在探测去泛素化酶(DUB)活性和泛素链连接特异性方面非常有用。在这里,我们描述了一个详细的协议,合成一类新的双泛素DUB探针。在该方法中,两个泛素部分通过大小类似于天然连接的接头连接,并且含有用于捕获DUB活性位点半胱氨酸的迈克尔受体。还描述了用于产生接头分子的详细程序。
Activity-based diubiquitin probes are highly useful in probing the deubiquitinase (DUB) activity and ubiquitin chain linkage specificity. Here we describe a detailed protocol to synthesize a new class of diubiquitin DUB probes. In this method, two ubiquitin moieties are connected through a linker resembling the native linkage in size and containing a Michael acceptor for trapping the DUB active-site cysteine. Detailed procedures for generating the linker molecule are also described.
