"Restoration of replication phenotype of lamivudine-resistant hepatitis B virus mutants by compensatory changes in the ""fingers"" subdomain of the viral polymerase selected as a consequence of mutations in the overlapping S gene."
Abstract: The LMV-resistant HBV mutants rtM204I and rtL180M/M204V produced substantially weaker HBV DNA replicative intermediate signals by Southern blot analysis and less total intracellular HBV DNA by real-time PCR compared to wild-type virus.
Abstract: The two most common LMV-resistant mutants produce changes in the viral polymerase protein (rt) of rtM204I and rtL180M/M204V (previously rtM550I and rtL526M/
Hepatitis B virus resistance to lamivudine and its clinical implications.
Abstract: These mutations are found at codon (or AA) rtL180M and rtM204V/I in the reverse transcriptase (RT) domain of the HBV polymerase for all genotypes according to a new standardized RT domain numbering system.
Nomenclature for antiviral-resistant human hepatitis B virus mutations in the polymerase region.
Abstract: In this proposal, the HBV rt domain starts with the highly conserved EDWGPCDEHG motif, contains 344 amino acids, and the lamivudine-related resistance mutations are found at amino acid rtL180M (previously amino acid 528, 526, 515, or 525) and rtM204V/I (previously 552, 550, 539, or 549).
