Differential inhibition of RNA editing in hepatitis delta virus genotype III by the short and long forms of hepatitis delta antigen.

Abstract excerpt

Hepatitis delta virus (HDV) produces two essential forms of the sole viral protein from the same open reading frame by using host RNA editing activity at the amber/W site in the antigenomic RNA. The roles of these two forms, HDAg-S and HDAg-L, are opposed. HDAg-S is required for viral RNA replication, whereas HDAg-L, which is produced as a result of editing, inhibits viral RNA replication and is required for...
