SLC10A1 and infection: Upon infection of hepatocytes by exploiting the hepatocyte-specific receptor sodium taurocholate cotransporting polypeptide (NTCP), the viral rcDNA genome is transported into the nucleus to form the covalently closed circular DNA (cccDNA), which served as the template for transcription of all viral RNAs, including the 3.5-kb precore (pc) and pregenomic (pg) RNA, 2.4/2.1-kb surface mRNAs, and 0.7-kb X mRNA [4].
