Reaction Schemes
The enzyme catalyzes two essential functions in the SUMO pathway: processing of full-length SUMO-1, SUMO-2 and SUMO-3 to their mature forms and deconjugation of SUMO1, SUMO2 and SUMO3 from targeted proteins. Deconjugates SUMO-2 from mitotic kinase Aurora-B. Deconjugates SUMO-1 from Mdm2, an protein critical for genome integrity in P53-dependent stress response. Cleavage of Gly97-/-His98 bond in the SUMO-1 precursor with release of the propeptide His-Ser-Thr-Val. Cleavage of Gly93-/-Val94 bond in the SUMO-2 precursor with release of the propeptide Val94-Thyr. Cleavage of the Gly92-/-Val93 in the SUMO-3 precursor with release of the propeptide Pro-Glu-Ser-Ser-Leu-Ala-Gly-His-Ser-Phe.

-
specifically deconjugates SUMO from mitotic kinase Aurora-B. Lys202 on human Aurora-B is preferentially modified by SUMO, and enhancement of SUMOylation in cells facilitates Aurora-B autophosphorylation, which is essential for its activation. Conversely, SENP2-mediated deSUMOylation of Aurora-B down-regulates its autophosphorylation in cells and also impairs its re-activation in Aurora inhibitor VX-680-treated mitotic cells. Poly-SUMO-2 conjugation of Aurora-B occurs during the M phase ofthe cell cycle, and both SUMO-2 and PIAS3 are localized adjacent to Aurora-B in the kinetochores in early mitosis. Aurora-B is a mitotic SUMO substrate and its kinase activity is fine-tuned by the SUMO system

LITERATURE
evolution
the enzyme belongs to the SENP/ULP protease family
malfunction
RNA interference SENP2 knockdown produces no detectable phenotypes, while overexpression of SENP2, but not other SUMO-specific isopeptidases, causes a defect in chromosome congression that depends on its pre­cise kinetochore targeting. Isozyme SENP2 overexpression uniquely induces prometaphase arrest

LITERATURE
ubiquitination
SENP2 can be polyubiquitinated in vivo and degraded through proteolysis. Restricting SENP2 in the nucleus by mutations in the nuclear export signal (NES) impairs its polyubiquitination, whereas a cytoplasm-localized SENP2 made by introducing mutations in the nuclear localization signal (NLS) can be efficiently polyubiquitinated, suggesting that SENP2 is ubiquitinated in the cytoplasm

recombinant chimeric mutant SENP2 C548S-loop1 in complex with SUMO2, X-ray diffraction structure determination and analysis at 2.15 A resolution
Senp2 crystallization is performed at 4°C using sitting and hanging drop vapor diffusion methods. X-ray structures of Senp2 catalytic protease domain and of a covalent thiohemiacetal transition-state complex obtained between the Senp2 catalytic domain and SUMO-1 reveales details of the respective protease and substrate surfaces utilized in interactions between these two proteins. Comparative biochemical and structural analysis between Senp2 and the yeast SUMO protease Ulp1 reveales differential abilities to process SUMO-1, SUMO-2, and SUMO-3 in maturation and deconjugation reactions
X-ray structures are determined for a catalytically inert SENP2 protease domain in complex with conjugated RanGAP1-SUMO-1 or RanGAP1-SUMO-2, or in complex with SUMO-2 or SUMO-3 precursors

SENP2 expression is significantly downregulated in clinical osteosarcoma tissues compared with adjacent normal samples. Ectopic expression of SENP2 results in the suppression of proliferation, migration and invasion in osteosarcoma cells, whereas SENP2 knockdown has the opposite effect. SENP2 is associated with the proteaxadsome-dependent ubiquitination and degradation of SRY-box-9 (SOX9). SOX9 silencing impairs SENP2-depletion-induced accelerated cell growth and migration
