    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(fù)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(zhì)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：
    Plays a central role during spermatogenesis by repressing transposable elements and preventing their mobilization, which is essential for the germline integrity. Acts via the piRNA metabolic process, which mediates the repression of transposable elements during meiosis by forming complexes composed of piRNAs and Piwi proteins and governs the methylation and subsequent repression of transposons. Directly binds piRNAs, a class of 24 to 30 nucleotide RNAs that are generated by a Dicer-independent mechanism and are primarily derived from transposons and other repeated sequence elements. Associates with secondary piRNAs antisense and PIWIL2/MILI is required for such association. The piRNA process acts upstream of known mediators of DNA methylation. Does not show endonuclease activity. Plays a key role in the piRNA amplification loop, also named ping-pong amplification cycle, by acting as a 'slicer-incompetent' component that loads cleaved piRNAs from the 'slicer-competent' component PIWIL2 and target them on genomic transposon loci in the nucleus. May be involved in the chromatin-modifying pathway by inducing 'Lys-9' methylation of histone H3 at some loci. In addition to its role in germline, PIWIL4 also plays a role in the regulation of somatic cells activities. Plays a role in pancreatic beta cell function and insulin secretion. Involved in maintaining cell morphology and functional integrity of retinal epithelial through Akt/GSK3alpha/beta signaling pathway. When overexpressed, acts as an oncogene by inhibition of apoptosis and promotion of cells proliferation in tumors.

    1. these findings revealed that Piwil4 is a novel regulator of ER signaling that could be targeted to inhibit breast cancer growth and migration. PMID: 30226541
    2. Results revealed that Piwil4 exhibits lower expression in the cell nucleus than in the cytoplasm. Along with nuclear location of PIWIL2, PIWIL4 expression is associated with worse prognosis of hepatocellular carcinoma. PMID: 27894076
    3. HIWI2 is aberrantly expressed in cells of the Retinoblastoma (RB) line (Y79) and silencing of HIWI2 downregulates OTX2, suggesting that HIWI2 might affects cell cycle and plays a role in the progression of RB. PMID: 28861107
    4. data delineate MIWI2-dependent functions outside of the germline and demonstrate the presence of distinct subsets of airway multiciliated cells that can be discriminated by MIWI2 expression. PMID: 28920925
    5. PIWIL2 and PIWIL4 genes expression in synovial fibroblasts of the rheumatoid arthritis patients.PIWIL4 does not regulate methylation or expression of LINE-1. PMID: 27893851
    6. MiR-384 functioned as tumor suppressor by decreasing PIWIL4 in glioma cell lines. PMID: 27058823
    7. study demonstrates the presence of PIWI-like proteins in somatic cells and the possible role of HIWI2 in preserving the functional integrity of epithelial cells probably by modulating the phosphorylation status of Akt. PMID: 28025795
    8. PIWIL4 is highly expressed in both breast cancer tissues and the cytoplasm of MDA-MB-231 cells derived from breast cancer. Reducing PIWIL4 expression drastically impairs the migration ability of MDA-MB-231 cells, significantly increases their apoptosis, and mildly affects their proliferation. PMID: 26957540
    9. Results show that three CpG loci within FYN were hypermethylated in obese individuals, while obesity was associated with lower methylation of CpG loci within PIWIL4 and TAOK3. PMID: 26646899
    10. study to evaluate frequency of PIWIL4 genetic variants in order to better define the relationship between PIWIL4 SNPs and defective spermatogenesis and specific spermatogenic disorders; results suggest genetic and epigenetic alterations that affect the PIWI pathway contribute to unsuccessful sperm production PMID: 24969058
    11. Data suggest that MIWI2 and MIWI2-associated piRNAs have functions beyond TE suppression. PMID: 24464225
    12. Immunoprecipitation of Hiwi2 from MDAMB231 cancer cells enriches for piRNAs that are predominantly derived from processed tRNAs and expressed genes. PMID: 25038252
    13. associations were determined between the Piwi-like family member expression levels and clinicopathological parameters of ccRCC, suggesting a potential role for these genes/proteins in ccRCC diagnostics and tumorigenesis PMID: 24509249
    14. PIWIL4 might play an oncogenic role in cervical cancer PMID: 22483988
    15. An SNP in the 3'untranslated region of HIWI2 and a non-synonymous SNP in HIWI3 were significantly associated with an altered risk of oligozoospermia. PMID: 20940137
    16. EIF2C2-4 and PIWIL4 appear increased in advanced tumors with distant metastasis, suggesting they may promote tumor invasion PMID: 20146808
