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(chǎn)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(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(xiàng)：

Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

靶點(diǎn)詳情

功能：

Rex escorts unspliced gag-pro-pol and singly spliced env mRNAs out of the nucleus of infected cells. These mRNAs carry a recognition sequence called Rex responsive element (RxRE or XRE) located at the 3' region of the long terminal repeat (LTR). This function is essential since most HTLV proteins are translated from unspliced or partially spliced pre-mRNAs that cannot exit the nucleus by the pathway used by fully processed cellular mRNAs. Rex itself is translated from a fully spliced mRNA that probably readily exits the nucleus. Rex's nuclear localization signal (NLS) binds directly to KPNB1/importin beta-1 without previous binding to KPNA1/importin alpha-1. KPNB1 binds to the GDP bound form of RAN (Ran-GDP) and targets Rex to the nucleus. In the nucleus, the conversion from Ran-GDP to Ran-GTP dissociates Rex from KPNB1 and allows Rex's binding to the RRE in viral pre-mRNAs. Rex multimerizes on the RRE via cooperative assembly. This multimerization is critical for its full biological activity, since it may shield the viral RNA from being spliced or down-regulated, and probably exposes Rex's nuclear export signal (NES) to the surface. Rex can then form a complex with XPO1/CRM1, RANBP3 and Ran-GTP, leading to nuclear export of the complex. Conversion from Ran-GTP to Ran-GDP mediates dissociation of the Rex/RRE/XPO1/RANBP3/RAN complex, so that Rex can return to the nucleus for a subsequent round of export.
