  • 产品描述：

    The Recombinant Zaire Ebola virus VP35 protein is a protein encoded by recombinant DNA that was cloned in an expression vector that supported the expression of VP35 gene. This recombinant VP35 protein was expressed in the host. The expression region is 1-340aa of the Zaire Ebola virus VP35. In the production, the expression vector contains N-terminal 10xHis tag and C-terminal Myc tag. Every production step was performed with a strict QC system. The purity of this protein is 90%+ determined by SDS-PAGE.

    VP35, an essential viral RNA-dependent RNA polymerase cofactor, is indispensable for Ebola viral replication and host innate immune escape. VP35 was demonstrated to be phosphorylated at Serine/Threonine by immunoblotting, and the major phosphorylation sites was S187, S205, T206, S208 and S317 as revealed by LC-MS/MS. VP35, which contains both dsRNA-binding and oligomerization domains, is an essential polymerase cofactor and plays immune antagonist roles in host cells by targeting RIG-I-like receptors, PKR, and dsRNA. Previous work indicates VP35 binds synthetic dsRNA molecules in vitro and can inhibit IFN induction mediated by these dsRNAs in cell culture. Several studies clearly demonstrate the correlation between VP35 dsRNA-binding activity and its ability to inhibit type I IFN responses. In addition to acting as an immune antagonist, VP35 also has diverse functions during virus replication. Since virulence is correlated to the ability of the virus to suppress the innate immune response and VP35 is one of the major viral players in suppressing the host innate immune response.

  • 功能：
    Plays an essential role in viral RNA synthesis and also a role in suppressing innate immune signaling. Acts as a polymerase cofactor in the RNA polymerase transcription and replication complexes. Serves as nucleoprotein/NP monomer chaperone prior to the formation of the large oligomeric RNA-bound complexes. Regulates RNA synthesis by modulating NP-RNA interactions and interacting with DYNLL1. VP35-NP interaction controls the switch between RNA-bound NP and free NP and thus the switch between genome replication and genome packaging into the nucleocapsid. Prevents establishment of cellular antiviral state, thereby suppressing host DC maturation. Acts by inhibiting host DDX58/RIG-I activation both by shielding dsRNA from detection and by preventing PRKRA binding to DDX58. Blocks virus-induced phosphorylation and activation of interferon regulatory factor 3/IRF3, a transcription factor critical for the induction of interferons alpha and beta. This blockage is produced through the interaction with and inhibition of host IKBKE and TBK1, producing a strong inhibition of the phosphorylation and activation of IRF3. Also inhibits the antiviral effect mediated by the host interferon-induced, double-stranded RNA-activated protein kinase EIF2AK2/PKR. Increases PIAS1-mediated SUMOylation of IRF7, thereby repressing interferon transcription. Also acts as a suppressor of RNA silencing by interacting with host DICER1, TARBP2/TRBP and PRKRA/PACT. As a dimer, binds and sequesters dsRNA contributing to the inhibition of interferon production.
