  • IHC image of CSB-PA753588LA01HU diluted at 1:400 and staining in paraffin-embedded human appendix tissue performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a biotinylated secondary antibody and visualized using an HRP conjugated SP system.

Target Background

Function
Negative regulator of the non-canonical NF-kappa-B pathway that acts by mediating deubiquitination of TRAF3, an inhibitor of the NF-kappa-B pathway, thereby acting as a negative regulator of B-cell responses. In response to non-canonical NF-kappa-B stimuli, deubiquitinates 'Lys-48'-linked polyubiquitin chains of TRAF3, preventing TRAF3 proteolysis and over-activation of non-canonical NF-kappa-B. Negatively regulates mucosal immunity against infections. Deubiquitinates ZAP70, and thereby regulates T cell receptor (TCR) signaling that leads to the activation of NF-kappa-B. Plays a role in T cell homeostasis and is required for normal T cell responses, including production of IFNG and IL2. Mediates deubiquitination of EGFR. Has deubiquitinating activity toward 'Lys-11', 'Lys-48' and 'Lys-63'-linked polyubiquitin chains. Has a much higher catalytic rate with 'Lys-11'-linked polyubiquitin chains (in vitro); however the physiological significance of these data are unsure. Hydrolyzes both linear and branched forms of polyubiquitin.
Gene References into Functions
  1. Study demonstrated that the N-terminal UBA domain is crucial for the function of Cezanne during NF-kappaB activation. Cezanne is recognized and recruited into activated TNFR complex by specifically binding to polyubiquitinated signaling proteins after TNF stimulation through its N-terminal polyubiquitin binding site. PMID: 28817177
  2. Cezanne may be a novel antioncogene that has a pivotal role in the invasion of hepatocellular carcinoma and contribute to the selection of patients who may benefit from adjuvant transcatheter arterial chemoembolization to prevent recurrence. PMID: 28880268
  3. TRAF2 and OTUD7B govern a ubiquitin-dependent switch that regulates mTORC2 signalling PMID: 28489822
  4. Findings indicated both cezanne-1 and IGF1R expressions were negative independent predictive factors for the prognosis of lung adenocarcinoma, respectively. There was a close positive interrelationship between cezanne-1 and IGF1R expression. PMID: 28365890
  5. expression of OTUD7B and NIK were negatively correlated in non-small cell lung cancer tumor samples. The higher expression of OTUD7B was associated with smaller tumor size, less lymph node metastasis and earlier TNM stage. the high expression of OTUD7B was associated with good prognosis of NSCLC patients, and a high OTUD7B/low NIK index can predict even better prognosis. also, OTUD7B is an independent markers of survival. PMID: 27499151
  6. crystal structures of Cezanne alone and in complex with monoubiquitin and Lys11-linked diubiquitin, in combination with hydrogen-deuterium exchange mass spectrometry, enable a reconstruction of the enzymatic cycle in great detail PMID: 27732584
  7. these data reveal a novel mechanism for the regulation of the expression of HIF2a, demonstrating that the HIF2a promoter is regulated by E2F1 directly and that Cezanne regulates HIF2a expression through control of E2F1 levels PMID: 26148512
  8. Taken together, these results suggest that hepatitis C virus NS5A protein interacts with OTUD7B, thereby modulating its deubiquitinase activity. PMID: 26112491
  9. Cezanne has a pivotal role in tumor progression and prognosis, and may act as a potential prognostic biomarker for survival in hepatocellular carcinoma patients. PMID: 25638165
  10. data suggest that Cezanne is essential for HIF-1alpha protein stability and that loss of Cezanne stimulates HIF-1alpha degradation via proteasome-independent routes, possibly through chaperone-mediated autophagy. PMID: 25355043
  11. Genome wide association study shows evidence of association between mammographic density and SNPs in high linkage disequilibrium with rs11205277, rs11205303 in gene MTMR11 and rs67807996 in gene OTUD7B. PMID: 25353672
  12. Inflammatory responses to ischemia are controlled by a balance between TRAF6 ubiquitination and deubiquitination, and Cezanne is a key regulator of this process. PMID: 23564640
  13. identified a deubiquitinating enzyme, Cezanne-1, that opposes receptor degradation and enhances EGFR signaling PMID: 22179831
  14. There is an excessive inflammatory response but insufficient up-regulation of A20 expression in inflammatory bowel disease patients. PMID: 21624200
  15. DJ-1 enhances cell survival through the binding of Cezanne, a negative regulator of NF-kappaB. PMID: 21097510
  16. Cezanne is identified as the first deubiquitinase with Lys11-linkage preference. PMID: 20622874
  17. cleaves ubiquitin from proteins PMID: 12682062
  18. Cezanne forms a novel negative feedback loop in pro-inflammatory signaling and that it suppresses NF-kappaB activation by targeting RIP1 signaling intermediaries for deubiquitination PMID: 18178551
  19. H(2)O(2) prolongs NF-kappaB activation in co-stimulated cells by suppressing the negative regulatory functions of Cezanne and IkappaBalpha. PMID: 18474597
