  • FormLiquid
  • Additional notes

    - First try to dissolve a small amount of peptide in either water or buffer. The more charged residues on a peptide, the more soluble it is in aqueous solutions.
    - If the peptide doesn’t dissolve try an organic solvent e.g. DMSO, then dilute using water or buffer.
    - Consider that any solvent used must be compatible with your assay. If a peptide does not dissolve and you need to recover it, lyophilise to remove the solvent.
    - Gentle warming and sonication can effectively aid peptide solubilisation. If the solution is cloudy or has gelled the peptide may be in suspension rather than solubilised.
    - Peptides containing cysteine are easily oxidised, so should be prepared in solution just prior to use.

  • FunctionInvolved 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 specificityPresent in vascular smooth cells (at protein level).
  • Sequence similaritiesBelongs to the helicase family.
    Contains 2 CARD domains.
    Contains 1 helicase ATP-binding domain.
    Contains 1 helicase C-terminal domain.
  • DomainThe 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 localizationCytoplasm. Colocalized with TRIM25 at cytoplasmic perinuclear bodies.
  • Information by UniProt
