The mechanism of APOBEC3 proteins in the control of HBV infection, however, is less clear," investigators in Hangzhou, People's Republic of China report. "Here we report that APOBEC3B (A3B) displays dual inhibitory effects on both HBsAg and HBeAg expression as well as HBV core-associated DNA synthesis. Heterogeneous nuclear ribonucleoprotein K (hnRNP K), a positive regulator of HBV expression, has been identified as a major interaction partner of A3B protein. A3B protein...
