已经确定了一组相扑靶蛋白。因此,人们对研究细胞中的sumoylation和相互作用的兴趣越来越大。当怀疑蛋白质或相互作用的Sumoylation时,通常将使用抗SUMO和抗目标蛋白抗体进行标准的共免疫沉淀分析。然而,由于异肽酶的活性,内源性sumoylated蛋白的鉴定是具有挑战性的,并且在给定时间通常只会仅将一小部分靶蛋白组成。本文中,我们简要概述了几个重要步骤,以确保成功进行共免疫沉淀分析以检测可能的Sumoylation。
A diverse set of SUMO target proteins has been identified. Therefore, there is a growing interest in studying sumoylation and SUMO interactions in cells. When the sumoylation of a protein or a SUMO-interaction is suspected, a standard co-immunoprecipitation analysis using anti-SUMO and anti-target protein antibody is usually performed as a first step. However, the identification of endogenous sumoylated proteins is challenging because of the activity of isopeptidases, and often, only a small fraction of a target protein is sumoylated at a given time. Herein, we briefly summarize several important steps to ensure a successful co-immunoprecipitation analysis to detect possible sumoylation.
