Outline of Final Research Achievements |
Molecular mechanisms underlying hepatitis B virus (HBV) life cycle has not been fully clarified. In this study, we identified host factors regulating HBV life cycle and analyzed its regulation mechanism by using cell models efficiently supporting HBV infection and replication. Through the identification of nocodazole that inhibited HBV replication, we revealed that cellular microtubules were important for the multimerization of core protein and post-translational modification of tubulin regulated HBV replication. We also identified cellular kinases that regulated HBV entry process. These findings provide information important for understanding the molecular mechanisms of virus-host interaction.
