    • IHC image of CSB-RA930964A0HU diluted at 1:100 and staining in paraffin-embedded human ovarian 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℃ overnight. The primary is detected by a Goat anti-rabbit IgG polymer labeled by HRP and visualized using 0.05% DAB.

  • 产品描述：

    XPO1 is a member of the karyopherin family of proteins that transports macromolecules from the nucleus to the cytoplasm. XPO1 is involved in protein trafficking between the nucleus and the cytoplasm, as well as ribosomal RNA, specific necessary mRNAs, mRNA stability, drug response, and ribosomal biogenesis. Additionally, XPO1-mediated nuclear export has been linked to a variety of diseases, including cancer, inflammation, and viral infection. XPO1 impacts the loss of control in cancer cell proliferation via numerous mechanisms and plays a function in cell proliferation control.

    The first step in the preparation of recombinant XPO1 antibody is to obtain the XPO1 antibody gene. The heavy and light chain genes of the antibody were constructed into a plasma vector and then transfected into suspended mammalian cells transiently. After expression verification, cell supernatant was collected in expanded culture and purified recombinant XPO1 antibody was obtained using Affinity-chromatography. This recombinant XPO1 antibody has been validated for the detection of XPO1 protein from Human in the ELISA, IHC.

  • 功能：
    Mediates the nuclear export of cellular proteins (cargos) bearing a leucine-rich nuclear export signal (NES) and of RNAs. In the nucleus, in association with RANBP3, binds cooperatively to the NES on its target protein and to the GTPase RAN in its active GTP-bound form (Ran-GTP). Docking of this complex to the nuclear pore complex (NPC) is mediated through binding to nucleoporins. Upon transit of a nuclear export complex into the cytoplasm, disassembling of the complex and hydrolysis of Ran-GTP to Ran-GDP (induced by RANBP1 and RANGAP1, respectively) cause release of the cargo from the export receptor. The directionality of nuclear export is thought to be conferred by an asymmetric distribution of the GTP- and GDP-bound forms of Ran between the cytoplasm and nucleus. Involved in U3 snoRNA transport from Cajal bodies to nucleoli. Binds to late precursor U3 snoRNA bearing a TMG cap.; (Microbial infection) Mediates the export of unspliced or incompletely spliced RNAs out of the nucleus from different viruses including HIV-1, HTLV-1 and influenza A. Interacts with, and mediates the nuclear export of HIV-1 Rev and HTLV-1 Rex proteins. Involved in HTLV-1 Rex multimerization.

    4. The subcellular distributions of IkappaB and NFkappaB are indicative of carcinogenesis. Inhibition of XPO1 results in intranuclear retention of IkappaB, which inhibits NFkappaB and thereby provides a novel mechanism for drug therapy in sarcoma. This effect can be further enhanced in relatively selinexor-resistant sarcoma cell lines by pretreatment with the proteasome inhibitor carfilzomib. PMID: 28314790
