A little guide for advanced search:

  • Tip 1. You can use quotes "" to search for an exact expression.
    Example: "cell division"
  • Tip 2. You can use + symbol to restrict results containing all words.
    Example: +cell +stem
  • Tip 3. You can use + and - symbols to force inclusion or exclusion of specific words.
    Example: +cell -stem
e.g. searching for members in projects tagged cancer

The nonstructural 5A (NS5A) protein of hepatitis C virus (HCV) genotype 1 is thought to interact with several cellular proteins, including the double-stranded RNA-dependent protein kinase (PKR) induced by interferon (IFN). The PKR-binding domain (PKR-BD; aa 2209-2274), including the IFN sensitivity-determining region (aa 2209-2248) and other regions, could be linked to IFN resistance. Thus, the entire NS5A sequence of 27 isolates of HCV genotype 3a was investigated in relation to the clinical response to IFN. The NS5A 3a protein presented a low variability with some specific variable regions. Differential analysis between IFN-resistant and -sensitive isolates identified 5 regions in NS5A, 2 of them inside the PKR-BD and another around the variable 3 region. However, using the yeast growth suppression assay, no interaction was found between 5 resistant NS5A 3a proteins and PKR. Some amino acid changes of the NS5A protein of genotype 3a seemed to relate to IFN resistance independently of the PKR pathway.
