Model of interaction between large envelope proteins and the sodium-taurocholate cotransporting polypeptide. A: Schematic diagram of hepatitis B virus envelope proteins: Small (S), Middle (M) and Large (L) envelope proteins. B: Representation of the interaction between the viral preS1 protein and its host receptor in hepatocytes, sodium-taurocholate cotransporting polypeptide (NTCP), modified from the model proposed by Urban[53]. The 2 domains analyzed in this study, the NTCP-interacting and virion morphogenesis (VM) domains, are indicated in the L protein. Numbering is based on the HBV genotype D consensus sequence. myr: Myristic acid; HBV: Hepatitis B virus.
