  • 蛋白標簽：
    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.
  • 產品提供形式：
    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.
  • 復溶：
    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.
  • 儲存條件：
    Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
  • 保質期：
    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.
  • 貨期：
    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.
  • 注意事項：
    Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
  • Datasheet ：

靶點詳情

  • 功能：
    Involved in nonsense-mediated decay (NMD) of mRNAs containing premature stop codons by associating with the nuclear exon junction complex (EJC) and serving as link between the EJC core and NMD machinery. Recruits UPF2 at the cytoplasmic side of the nuclear envelope and the subsequent formation of an UPF1-UPF2-UPF3 surveillance complex (including UPF1 bound to release factors at the stalled ribosome) is believed to activate NMD. In cooperation with UPF2 stimulates both ATPase and RNA helicase activities of UPF1. Binds spliced mRNA upstream of exon-exon junctions. In vitro, stimulates translation; the function is independent of association with UPF2 and components of the EJC core.
  • 基因功能參考文獻：
    1. The authors discovered that UPF3B (i) interacts with the release factors, (ii) delays translation termination and (iii) dissociates post-termination ribosomal complexes that are devoid of the nascent peptide. PMID: 28899899
    2. UPF3B gene mutation is associated with Lujan-Fryns syndrome. PMID: 26358559
    3. the neurodevelopmental phenotype of UPF3B missense mutation is caused by impairment of nonsense-mediated mRNA decay pathway function altering neuronal differentiation. PMID: 26012578
    4. These findings indicate that SATB2 activates UPF3B expression through binding to its promoter. PMID: 23925499
    5. Data indicate the mutation p.R430X of UPF3B gene as the genetic etiology in the mental retardation pedigree. PMID: 22957832
    6. results demonstrate that the UPF3B-dependent NMD pathway is a major regulator of the transcriptome and that its targets have important roles in neuronal cells. PMID: 22182939
    7. The two cases with renal dysplasia and developmental delay showed remarkable clinical variability despite having the same mutation in UPF3B. PMID: 22609145
    8. Our results demonstrate that in addition to Lujan-Fryns and FG syndromes, UPF3B protein truncation mutations can cause also nonspecific XLMR. PMID: 19238151
    9. 3.4 A resolution crystal structure of a minimal UPF3b-EJC assembly, consisting of the interacting domains of five proteins (UPF3b, MAGO, Y14, eIF4AIII, and Barentsz) together with RNA and adenylyl-imidodiphosphate PMID: 20479275
    10. A conserved domain of hUpf3b mediates an interaction with the EJC protein Y14. Y14 is required for nonsense-mediated decay induced by tethered hUpf3b. PMID: 12718880
    11. The protein region that mediates this interaction and discriminates between hUpf3a and hUpf3b in NMD function is located in the C-terminal domain and fully contained within a small sequence that is highly conserved in Upf3b but not Upf3a proteins PMID: 16601204
    12. UPF3B induces nonsense mediated decay in the cytoplasm PMID: 17194930
    13. Three mutations lead to the introduction of a premature termination codon and subsequent nonsense-mediated mRNA decay of mutant UPF3B mRNA. PMID: 17704778
    14. UPF2 and UPF3b cooperatively stimulate both ATPase and RNA helicase activities of UPF1. PMID: 18066079
    15. Results suggest that UPF3A levels are tightly regulated by a post-transcriptional switch to maintain appropriate levels of NMD substrates in cells containing different levels of UPF3B. PMID: 19503078
    16. binds to spliced mRNAs upstream of exon-exon junctions; is part of mRNP complexes that are ready for nuclear export and that participate in nonsense-mediated mRNA decay PMID: 11546873
    17. binds RNPS1 protein, part of the postsplicing complex deposited 5' to exon-exon junctions PMID: 11546874
