Target

  • Function

    Involved in innate immune defense against viruses. Upon interaction with intracellular dsRNA produced during viral replication, triggers a transduction cascade involving MAVS/IPS1, which results in the activation of NF-kappa-B, IRF3 and IRF7 and the induction of the expression of antiviral cytokines such as IFN-beta and RANTES (CCL5). Detects dsRNA produced from non-self dsDNA by RNA polymerase III, such as Epstein-Barr virus-encoded RNAs (EBERs). Essential for the production of interferons in response to RNA viruses including paramyxoviruses, influenza viruses, Japanese encephalitis virus and HCV.
  • Tissue specificity

    Present in vascular smooth cells (at protein level).
  • Sequence similarities

    Belongs to the helicase family.
    Contains 2 CARD domains.
    Contains 1 helicase ATP-binding domain.
    Contains 1 helicase C-terminal domain.
  • Domain

    The repressor domain controls homomultimerization and interaction with MAVS.
    The helicase domain is responsible for dsRNA recognition.
    The 2 CARD domains are responsible for interaction with and signaling through MAVS.
    The second CARD domain is the primary site for 'Lys-63'-linked ubiquitination.
  • Post-translational
    modifications

    Isgylated. Conjugated to ubiquitin-like protein ISG15 upon IFN-beta stimulation.
    Ubiquitinated. Undergoes 'Lys-63'-linked ubiquitination. Lys-172 is the critical site for TRIM25-mediated ubiquitination, for MAVS binding and to induce anti-viral signal transduction. Lys-154, Lys-164 and Lys-172 are critical sites for RNF135-mediated ubiquitination. Deubiquitinated by CYLD, a protease that selectively cleaves 'Lys-63'-linked ubiquitin chains.
  • Cellular localization

    Cytoplasm. Colocalized with TRIM25 at cytoplasmic perinuclear bodies.

Images

  • RIG-I/DDX58 was immunoprecipitated from 1mg of Jurkat (Human T cell leukemia cells from peripheral blood) whole cell lysate with ab180675 at 1/100 dilution. Western blot was performed from the immunoprecipitate using ab180675 at 1/1000 dilution. VeriBlot for IP Detection Reagent (HRP) (ab131366), was used for detection at 1/10000 dilution.

    Lane 1: Jurkat whole cell lysate 10ug (Input). Lane 2: ab180675 IP in Jurkat whole cell lysate. Lane 3: Rabbit monoclonal IgG (ab172730) instead of ab180675 in Jurkat whole cell lysate.
    Blocking and dilution buffer and concentration: 5% NFDM/TBST.
    Exposure time: 30 seconds.

    This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab180675).
