?
-
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

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
evolution
-
SUMO-specific protease 2 (SENP2) is a de-SUMOylation protease family member
additional information
-
SENP2 is a target of SUMO modification and has targeting preference for SUMO paralogues and substrates
physiological function
enzyme SENP2 is an important mediator of precise spatial and temporal control of sumoylation in mitosis required for chromosome segregation
physiological function
SENP2 inhibits nuclear translocation of beta-catenin, which targets the promotor of MMP13 to activate MMP13 to enhance bladder cancer cell metastasis
physiological function
SENP2 interacts with Smad4 through SENP2 residue 363-400. The same segment is also important for desumoylation of Smad4, and able to relieve sumoylation-mediated TGF-beta repression. The SENP2363-400 segment is critical for TGF-beta-induced cell migration, which is correlated with SENP2363-400 deletion mutant that fails to increase matrix metalloproteinase (MMP)-9 and epithelial-to-mesenchymal transition marker gene expression. The interaction and desumoylation between SENP2 and Smad4 promote cell migration in triple-negative breast cancer cells
physiological function
SENP2 knockdown results in a decrease of E-cadherin and an increase of N-cadherin and fibronectin at both transcript and protein levels. SENP2 overexpression results in deSUMOylation of TGF-betaR I in bladder cancer cells and suppresses TGF-beta signaling and TGF-beta-induced epithelial-mesenchymal transition. SENP2 regulates TGF-beta signaling partly through deSUMOylation of TGFbeta receptor I
malfunction
-
differential localization of nucleoporins upon codepletion of SENP1 and SENP2 in HeLa cells, immunohistochemic analysis, overview
malfunction
-
overexpression of enzyme SENP2 reduces the glucose uptake and lactate production, increasing the cellular ATP levels in MCF-7 cells. The MCF-7 cells overexpressing enzyme SENP2 exhibit decreased expression levels of key glycolytic enzymes and an increased rate of glucose oxidation compared with control MCF-7 cells, indicating inhibited glycolysis but enhanced oxidative mitochondrial respiration. The cells have a reduced amount of phosphorylated AKT
malfunction
-
silencing the expression of enzyme SENP2 significantly induces the expression of MMP13 , forced MMP13 expression is sufficient to restore cell invasion in SENP2 overexpressed T24 bladder cancer cells
malfunction
-
specifically, either RNAi depletion of SENP1/SENP2 or expression of dominantly interfering mutants of these proteins results in increased sumoylation of endogenous Nup153. Catalytically inactive SENP2 maintains specific attributes, although it has enhanced interaction with sumoylated Nup153, overview. Truncated SENP2CD is robustly modified by SUMO2
metabolism
-
SENP2 overexpression in MCF-7 cells reprograms glucose metabolism
metabolism
-
SENP2 protein is accumulated in response to activity-dependent stimuli which in turn mediated activity dependent-regulation of MEF2A deSUMOylation
physiological function
-
mitotic kinase Aurora-B is a mitotic SUMO substrate and its kinase activity is fine-tuned by the SUMO system
physiological function
-
enzyme SENP2 represses glycolysis and shifts glucose metabolic strategy, in part through inhibition of AKT phosphorylation, function of SENP2 in regulating glucose metabolism, overview
physiological function
-
SENP2, as well as SENP1, regulates the proper localization of nucleoporins, overview. The enzyme interacts with the nucleoporin Nup153 via a dual interface that includes a bridging interaction with the soluble transport receptor importin beta and a SUMO-mediated mechanism, and also with Nup358 and members of the Nup107-160 complex at distinct regions of SENP2 that can independently direct SENP2 to the nuclear rim. SENP1 and SENP2 are not required for localization of the transmembrane proteins nucleoporin POM121 and inner nuclear envelope protein Sun1 or expansion of the interphase nuclear envelope
physiological function
-
SENP2, but not SENP1, regulates MEF2A deSUMOylation in an activity dependent manner, enzyme SENP2 markedly enhances the transcription of MEF2A through directly deSUMOylation
physiological function
-
SUMO-specific protease 2 suppresses cell migration and invasion through selectively inhibiting the expression of MMP13 in bladder cancer cells, the enzyme has an indispensable role in the regulation of NF-kappaB transcriptional activation and Wnt signaling. The enzyme inhibits bladder cancer cells migration and invasion in vitro
physiological function
-
the SUMO proteases play roles both in processing SUMO during the biogenesis of this peptide moiety and also in reversing SUMO modification on specific targets to control the activities conferred by this posttranslational modification. Specificity of the role for SENP1 and SENP2 in maintaining desumoylation of Nup153
physiological function
-
ectopic expression of SENP2 results in the suppression of proliferation, migration and invasion in osteosarcoma cells, whereas SENP2 knockdown has the opposite effect
