dc.description.abstract | High mobility group nucleosomal binding domain 2 (HMGN2) is a small and unique non-histone protein that has many functions in a variety of cellular processes, including regulation of chromatin structure, transcription, and DNA repair. In addition, it may have other roles in antimicrobial activity, cell homing, and regulating cytokine release. Although the biochemical properties of HMGN2 protein are regulated by acetylation and phosphorylation, it is not yet known whether HMGN2 activity can also be regulated by SUMOylation. In this study, we demonstrated for the first time that HMGN2 is modified by covalent attachment of small ubiquitin-related modifier 1 (SUMO1) by pro-inflammatory signal and identified the major SUMOylated lysine residues that localize to the HMGN2 nucleosome-binding domain at Lys-17 and Lys-35. SENP1 can deSUMOylate SUMOylated HMGN2, and PIAS1 is the E3 ligase responsible for SUMOylation of HMGN2. Finally, using SUMO1-conjugated HMGN2 purified from a basal SUMOylation system in Escherichia coli, we demonstrated that SUMOylated HMGN2 has decreased the binding affinity to nucleosome core particles in comparison to unSUMOylated HMGN2. These observations potentially provide new perspectives for understanding the functions of HMGN2 in inflammatory reaction. | - |
