Identification of a highly conserved sequence element at the 3' terminus of hepatitis C virus genome RNA

Abstract

Previous reports suggest that the hepatitis C virus (HCV) genome RNA terminates with homopolymer tracts of either poly(U) or poly(A). By ligation of synthetic oligonucleotides followed by reverse transcription-PCR, cDNA cloning, and sequence analysis, we determined the 3'-terminal sequence of HCV genome RNA. Our results show that the HCV 3' nontranslated region consists of four elements (positive sense, 5' to 3'): (i) a short sequence with significant variability among genotypes, (ii) a homopolymeric poly(U) tract, (iii) a polypyrimidine stretch consisting of mainly U with interspersed C residues, (iv) a novel sequence of 98 bases. This latter nucleotide sequence is not present in human genomic DNA and is highly conserved among HCV genotypes. The 3'-terminal 46 bases are predicted to form a stable stem-loop structure. Using a quantitative-competitive reverse transcription-PCR assay, we show that a substantial fraction of HCV genome RNAs from a high- specific-infectivity inoculum contain this 3'-terminal sequence element. These results indicate that the HCV genome RNA terminates with a highly conserved RNA element which is likely to be required for authentic HCV replication and recovery of infectious RNA from cDNA.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
