Neddylation is an ubiquitin-like modification of proteins that affects the activity, stability and protein-protein interaction of its substrates. Apart from its role as a promoter for Cullin ring E3 ligase to positively regulate the ubiquitylation process, other functional studies about neddylation are still lacking. In this study, we developed a system to explore the impact of neddylation on changes in the subcellular localization of proteins at the omics level. By applying a method combining subcellular protein extraction and immunoprecipitation-mass spectrometry (IP-MS), 81 proteins with a tendency to shuttle between the cytoplasm and nucleus due to different neddylation levels were obtained. Among the 81 candidates, transforming growth factor-β (TGF-β)-activated kinase 1 (TAK1) and growth arrest and DNA damage protein 45a (Gadd45a) were confirmed as novel substrates of Nedd8, and neddylation promotes TAK1 nuclear import as well as Gadd45a nuclear export.
