Function[DESI1_MOUSE] Protease which deconjugates SUMO1, SUMO2 and SUMO3 from some substrate proteins. Has isopeptidase but not SUMO-processing activity. Desumoylates ZBTB46.[1] [2] Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedPost-translational modification by SUMO can be reversed by SENPs, the first known class of deSUMOylase. Recently, we identified a new deSUMOylating enzyme DeSI-1, which is distinct from SENPs and belongs to the putative deubiquitinating isopeptidase PPPDE superfamily. Herein, we report the crystal structure of DeSI-1, revealing that this enzyme forms a homodimer and that the groove between the two subunits is the active site harboring two absolutely conserved cysteine and histidine residues which form a catalytic dyad. We also show that DeSI-1 exhibits an extremely low endopeptidase activity toward precursor forms of SUMO-1 and SUMO-2, unlike SENPs. Proteins 2012. (c) 2012 Wiley-Liss, Inc.
