  • Function
    Single-stranded nucleic acid binding protein that binds preferentially to oligo dC. Major cellular poly(rC)-binding protein. Binds also poly(rU). Negatively regulates cellular antiviral responses mediated by MAVS signaling. It acts as an adapter between MAVS and the E3 ubiquitin ligase ITCH, therefore triggering MAVS ubiquitinationa and degradation.
  • Tissue specificity
    Detected in all tissues examined.
  • Sequence similarities
    Contains 3 KH domains.
  • Post-translational
    Phosphorylated. The non-phosphorylated form(s) exhibited the strongest poly(rC)-binding activity.
  • Cellular localization
    Nucleus. Cytoplasm. Loosely bound in the nucleus. May shuttle between the nucleus and the cytoplasm.
