1A92 - PubMed Abstract:
The hepatitis D virus (HDV) is a small satellite virus of hepatitis B virus (HBV). Coinfection with HBV and HDV causes severe liver disease in humans. The small 195 amino-acid form of the hepatitis delta antigen (HDAg) functions as a trans activator of HDV replication. A larger form of the protein containing a 19 amino acid C-terminal extension inhibits viral replication. Both of these functions are mediated in part by a stretch of amino acids predicted to form a coiled coil (residues 13-48) that is common to both forms. It is believed that HDAg forms dimers and higher ordered structures through this coiled-coil region.
