Abstract

The nucleotide sequence of the 5' nontranslated region of encephalomyocarditis virus (EMCV-Rueckert) was determined, and a consensus RNA structural model for this sequence (850 bases) and three other poly(C)-containing cardioviruses (mengovirus, EMCV-B, and EMCV-D) was created through reiterative use of a minimum-free-energy folding algorithm. The RNA elements within this region which contribute to translation of EMCV proteins were mapped in cell-free reactions programmed with cDNA-derived RNA transcripts. The data provide evidence that stem-loop motifs I, J and K, formed by viral bases 451 to 785, are important components of cap-independent translation. In contrast to other reports, a minimal role for stem-loop H (bases 406 to 444) in translational activity is indicated. Small 5' nontranslated region fragments (bases 667 to 797) containing the J and K motifs proved strong competitive inhibitors when added to cell-free reactions programmed with exogenous capped or uncapped mRNAs. The putative sequestering of required translational factors by this segment clearly contributes to translational activity, but also suggests a possible competitive mechanism for the down regulation of host protein synthesis during viral infection.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The polyC tract of the prototype elephant virus is shorter than reported for EMCV isolates such as the prototype Rueckert strain, but is on par with Mengo virus.

    “While this polyC tract is shorter than reported for EMCV isolates such as the prototype Rueckert strain (C115UCUCCCUC10) [38], it is on par with Mengo virus (C50UC10) [39].”
  • In the case of EMCV, it is thought to stem from competition between cap- and IRES-dependent translation, rather than to be a definitive shut-off.

    “Indeed, in the case of EMCV, it is thought to stem from competition between cap- and IRES-dependent translation, rather than to be a definitive shut-off.16,158”

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.
