  • 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.

靶點詳情

  • 功能：
    RNA-binding protein which binds to intronic polypyrimidine tracts and mediates negative regulation of exons splicing. May antagonize in a tissue-specific manner the ability of NOVA1 to activate exon selection. In addition to its function in pre-mRNA splicing, plays also a role in the regulation of translation.
  • 基因功能參考文獻：
    1. splicing regulation by Ptbp2 is critical for germ cell communication with Sertoli cells PMID: 28636946
    2. This knockin Ptbp1 rescued a forebrain-specific, but not a pan-neuronal, Ptbp2 knockout, demonstrating both redundant and distinct roles for the proteins. Many developmentally regulated exons exhibited different sensitivities to PTBP1 and PTBP2. PMID: 27926877
    3. Ptbp2 is an essential factor in heat stress-induced sperm cell injury and non-obstructive azoospermia. PMID: 29045475
    4. Ptbp2 ablation results in germ cell loss due to increased apoptosis of meiotic spermatocytes and postmeiotic arrest of spermatid differentiation. PMID: 26391954
    5. These results define a new genetic regulatory program, where PTBP2 acts to temporarily repress expression of adult protein isoforms until the final maturation of the neuron. PMID: 24448406
    6. Thus, Ptbp2 inhibition of a discrete set of adult neuronal exons underlies early brain development prior to neuronal differentiation and is essential for postnatal survival. PMID: 22802532
    7. The expression of PSD-95 during early neural development is controlled at the RNA level by two PTB proteins whose sequential downregulation is necessary for synapse maturation. PMID: 22246437
    8. The present study provides evidence that alternative neuronal nPTB and Fox-1/Fox-2 isoforms are also produced in lenses PMID: 21714144
    9. Regulation of the mutually exclusive exons 8a and 8 in the CaV1.2 calcium channel transcript by polypyrimidine tract-binding protein. PMID: 21282112
    10. Reduction of PTBP2 levels led to decreases in 7 of 10 of the mRNAs, to the repression of alternative splicing of introns, and to reductions in specific miRNAs. PMID: 20980688
    11. knock-down inhibits immunoglobulin class-switch recombination PMID: 21186367
    12. The predominant expression of REST4, HuB/C/D and nPTB in post-mitotic fiber cells, together with miR-124 expression in vertebrate lenses, was shown. PMID: 21139978
    13. PTBP2 is a trans-acting factor that helps to stabilize Pgk2 mRNA in male mouse germ cells. PMID: 17329592
    14. The post-transcriptional switch from PTB to nPTB controls a widespread alternative splicing program during neuronal development. PMID: 17606642
    15. PTBP2 was identified as a brain-expressed protein that interacts with the paraneoplastic target antigen Nova1 by yeast 2-hybrid, in vivo co-IP and co-localization in neurons. Functionally, the proteins antagonize each other in splicing assays. PMID: 10829067
