SUMO-interacting motifs (SIMs) play a central role in the fate of SUMO-modified proteins. Here we report a real-time SUMO-binding assay. It can be applied to the identification of SIMs and to screening for the identification of novel SUMO-binding proteins. Using this assay, we investigated the SIMs in SETDB1 and MCAF1 to gain insight into the assembly of SETDB1-MCAF1-mediated gene silencing.
