Tag Info
Tag type will be determined during the manufacturing process.
The tag type will be determined during production process. If you have specified tag type, please tell us and we will develop the specified tag preferentially.
Form
Lyophilized powder
Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.
Buffer before Lyophilization
Tris/PBS-based buffer, 6% Trehalose, pH 8.0
Reconstitution
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.
Troubleshooting and FAQs
Storage Condition
Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
Shelf Life
The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
Lead Time
Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
Note: All of our proteins are default shipped with normal blue ice packs, if you request to ship with dry ice, please communicate with us in advance and extra fees will be charged.
Notes
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Background

Function
Histone demethylase that demethylates 'Lys-4' and 'Lys-36' of histone H3, thereby playing a central role in histone code. Preferentially demethylates trimethylated H3 'Lys-4' and dimethylated H3 'Lys-36' residue while it has weak or no activity for mono- and tri-methylated H3 'Lys-36'. Preferentially binds the transcribed region of ribosomal RNA and represses the transcription of ribosomal RNA genes which inhibits cell growth and proliferation. May also serve as a substrate-recognition component of the SCF (SKP1-CUL1-F-box protein)-type E3 ubiquitin ligase complex (Probable).
Gene References into Functions
  1. Data indicate a cell regulatory mechanism through which lysine-specific demethylase 2B (KDM2B) promotes triple negative breast cancer (TNBC) cell proliferation by binding to the promoters of cell cycle inhibitors p15INK4B, p16INK4A, and p57KIP2. PMID: 30060056
  2. SS18-SSX1 deregulates developmental programs to drive transformation by hijacking a transcriptional repressive complex to aberrantly activate gene expression PMID: 29502955
  3. KDM2B regulates EZH2 and BMI1 in HCT116 colon tumor cells. Knockdown of this epigenetic factor induced potent up-regulation of the protein levels of the epithelial markers E-cadherin and ZO-1, while the mesenchymal marker N-cadherin was downregulated. PMID: 29772566
  4. These results establish a clear functional link between the epigenetic factor KDM2B and the regulation of cell adhesion and Rho-GTPases signaling that controls actin reorganization and cell migration. PMID: 29408056
  5. The apoptosis phenotype was partly dependent on HRK upregulation, as HRK knockdown significantly abrogated the sensitization. KDM2B-silenced tumors exhibited slower growth in vivo. Taken together, our findings suggest a novel mechanism, where the key apoptosis components are under epigenetic control of KDM2B in glioblastoma multiforme cells. PMID: 28661478
  6. Data indicate that the reduction of JmjC domain-containing histone demethylase 1B (JHDM1B) leads to a more aggressive cellular phenotype in mammary gland cells, by virtue of its negative regulatory activity on ribosome biogenesis. PMID: 28415746
  7. a novel regulatory role of KDM2B in autophagy and cell growth in gastric cancer cells, is reported. PMID: 28506929
  8. we identified KDM2B, a reader for methylated CpGs, as the target of miR-448 that represses glycolysis and promotes oxidative phosphorylation in gastric cancer PMID: 26989077
  9. High KDM2B expression is associated with Neuroblastomas. PMID: 28684529
  10. novel function of KDM2B in the negative regulation of cell proliferation by assembling an E3 ligase to targeting c-Fos protein degradation that is antagonized by mitogenic stimulations PMID: 26725323
  11. A missense mutation in the KDM2B gene is associated with malignant peripheral nerve sheath tumors. PMID: 28124441
  12. we propose histone demethylase KDM2B and histone methyltransferase SETD1B as the two most plausible candidate genes involved in intellectual disability, autism, epilepsy, and craniofacial anomalies PMID: 27106595
  13. NDY1/KDM2B functions as a master regulator of polycomb complexes and controls self-renewal of breast cancer stem cells. PMID: 24853546
  14. KDM2B is an important mediator of hematopoietic cell development and has opposing roles in tumor progression that are dependent on cellular context. PMID: 26808549
  15. Jhdm1b is a positive regulator of glycolysis, glutaminolysis, and pyrimidine synthesis in HeLa cells. PMID: 25877602
  16. The protein lysine demethylases Kdm2a and Kdm2b regulate the turnover of non-phosphorylated beta-catenin specifically within the nucleus via direct interaction with the fourth and fifth armadillo repeats. PMID: 26004508
  17. the KDM2B/let-7b/EZH2 axis is involved in epigenetic regulation in MDS, with direct effects on di- and tri-methylation of H3K27. PMID: 25225797
  18. KDM2B specifically recognizes non-methylated DNA in CpG islands and recruits the polycomb repressive complex 1 (PRC1). This contributes to histone H2A lysine 119 ubiquitylation and gene repression. PMID: 23256043
  19. Low JHDM1B expression is associated with breast cancers. PMID: 25273595
  20. KDM2B, an H3K36 histone demethylase implicated in bypass of cellular senescence and somatic cell reprogramming, is markedly overexpressed in PDAC, with levels increasing with disease grade and stage, and highest expression in metastases. PMID: 23321669
  21. It was found that JHDM1B mRNA is predominantly expressed in acute myeloid leukemia-derived aldehyde dehydrogenasehigh/CD34+ cells, and that aberrant expression of JHDM1B induces leukemia cell proliferation through modulation of cell cycle progression. PMID: 22086844
  22. a regulatory role of Fbxl10 in cell morphology, chemokine expression, and the metabolic control of fibroblasts. PMID: 22825849
  23. A novel functional role for FBXL10 as an anti-apoptotic molecule, and describe a new apoptotic-related pathway that involves NF-jB/FBXL10/c-Fos/ c-FLIP. PMID: 21252908
  24. Results demonstrate that Fbl10 is a key regulator of c-Jun function. PMID: 17704768
  25. identification of human JHDM1B as a nucleolar protein; JHDM1B preferentially binds the transcribed region of ribosomal DNA to repress the transcription of ribosomal RNA genes PMID: 17994099
  26. validated occurrence of an unusual TG 3' splice site in intron 15 PMID: 17672918
