The STUbL RNF4 regulates protein group SUMOylation by targeting the SUMO conjugation machinery
Abstract
SUMO and ubiquitin are key signal transducers in several cellular processes including the DNA-damage response. Here the authors describe a method for selective enrichment of ubiquitin substrates for E3 ligases from complex cellular proteomes and identify the SUMO conjugation machinery as direct RNF4 substrates.
