Abstract

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. Here, we briefly summarize several important steps to ensure a successful co-immunoprecipitation analysis to detect possible sumoylation.
