HCV NS5B-nucleolin interaction with subgenomic replicon permits replication

Published in Health and Medicine Week, May 18th, 2006

According to research from Japan, hepatitis C virus (HCV) nonstructural protein 5B (NS5B)-nucleolin interaction with subgenomic replicon permits HCV replication.

"We previously reported that nucleolin, a representative nucleolar marker, interacts with NS5B of HCV through two independent regions of NS5B, amino acids 208 to 214 and 500 to 506. We also showed that truncated nucleolin that harbors the NS5B-binding region inhibited the RNA-dependent RNA polymerase activity of NS5B in vitro, suggesting that nucleolin may be involved in HCV replication," wrote T. Shimakami and colleagues, Kanazawa University. "To address this question, we focused on NS5B amino acids 208 to...
