Assessment of SENP3-interacting proteins in hepatocytes treated with diethylnitrosamine by BioID assay.

ABSTRACT: SUMOylation of proteins regulates cell behaviors and is reversibly removed by small ubiquitin-like modifier (SUMO)-specific proteases (SENPs). The SENP family member SENP3 is involved in SUMO2/3 deconjugation and has been reported to sense cell stress and accumulate in several human cancer cells and macrophages. We previously reported that Senp3-knockout heterozygous mice showed smaller liver, but the pertinent mechanisms of SENP3 and SUMOylated substrates remain unclear. Thus, in this study, we investigated the interacting proteins with SENP3 and the alteration in hepatocytes treated with the xenobiotic diethylnitrosamine (DEN), which is specifically transformed in the liver and induces DNA double-strand breaks. Our data revealed that a certain amount of SENP3 was present in normal, untre
