Abstract

The interaction between a viral capsid and its genome governs crucial steps in the life cycle of a virus, such as assembly and genome uncoating. Tuning cargo-capsid interactions is also essential for successful design and cargo delivery in engineered viral systems. Here we investigate the interplay between cargo and capsid for the picorna-like Triatoma virus using a combined native mass spectrometry and atomic force microscopy approach. We propose a topology and assembly model in which heterotrimeric pentons that consist of five copies of structural proteins VP1, VP2 and VP3 are the free principal units of assembly. The interpenton contacts are established primarily by VP2. The dual role of the genome is first to stabilize the densely packed virion and, second, on an increase in pH to trigger uncoating by relaxing the stabilizing interactions with the capsid. Uncoating occurs through a labile intermediate state of the virion that reversibly disassembles into pentons with the concomitant release of protein VP4.

  • Native ion mobility mass spectrometry can monitor the dynamics of capsid morphology and stability as a function of pH and ionic strength.

    “As many capsid proteins self-assemble in vitro, native ion mobility MS can monitor the dynamics of capsid morphology and stability as a function of pH and ionic strength (28, 29).”
  • Native mass spectrometry and atomic force microscopy demonstrated that the single-stranded RNA genome of Triatoma virus stabilizes or triggers uncoating of the capsid in a pH-dependent fashion through electrostatic genome-capsid interactions.

    “For example, native MS and atomic force microscopy have demonstrated that the single-stranded RNA genome of the picorna-like Triatoma virus stabilizes or triggers uncoating of the capsid in a pH-dependent fashion through electrostatic genome-capsid interactions (29).”

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.
