Abstract:
The fact that HSP90 proteins and their chaperonin partners play an important role in epsilon RNA binding of duck HBV Pol protein during duck HBV replication has been reported. To elucidate the molecular basis of HBV Pol/HSP90 interaction, we have characterized the HSP90 interaction to HBV Pol. We found that human HBV Pol protein upon synthesis in rabbit reticulocyte lysate formed a complex with HSP90 in vitro as duck HBV Pol did. In addition, HSP90 protein was copurified with MBP/POL protein expressed in HepG2 cells, suggesting that human HBV Pol protein is associated with HSP90 in vivo. To localize the HSP90 interaction site region, several deletion mutants of HBV Pol translated in vitro were immunoprecipitated with anti-HSP90 antibody. The result indicates that C-terminal regions of the TP and RT domains interact with HSP90 independently.
