  • 产品描述：

    The recombinant human papillomavirus type 18 E7 protein is a fusion protein consists of the human papillomavirus type 18 E7 protein (1-105aa) partnered with the N-terminal 6xHis tag. It was produced in the E.coli. This recombinant human papillomavirus type 18 E7 protein's urity is greater than 90% determined by SDS-PAGE. After electrophoresis, there is a 19 kDa protein band presented on the gel.

    E7 proteins encoded by the cancer-associated alpha human papillomaviruses have potent transforming activities, which together with E6, are necessary but not sufficient to render their host squamous epithelial cell tumorigenic. HPV E7 proteins consist of approximately 100 amino acid residues. There are no cellular proteins that share extensive sequence similarities to E7. E7 proteins play a central role in the human papillomavirus life cycle, reprogramming the cellular environment to be conducive to viral replication. Some researches noted that the oncogenic activities of the high-risk alpha HPV E7 proteins represent functions related to the viral life cycle and/or arise as a consequence of a specific replication strategy that these viruses have adopted to establish a long-term persistent infection and/or produce viral progeny.

  • 功能：
    Plays a role in viral genome replication by driving entry of quiescent cells into the cell cycle. Stimulation of progression from G1 to S phase allows the virus to efficiently use the cellular DNA replicating machinery to achieve viral genome replication. E7 protein has both transforming and trans-activating activities. Induces the disassembly of the E2F1 transcription factor from RB1, with subsequent transcriptional activation of E2F1-regulated S-phase genes. Interferes with host histone deacetylation mediated by HDAC1 and HDAC2, leading to transcription activation. Plays also a role in the inhibition of both antiviral and antiproliferative functions of host interferon alpha. Interaction with host TMEM173/STING impairs the ability of TMEM173/STING to sense cytosolic DNA and promote the production of type I interferon (IFN-alpha and IFN-beta).
