Cell-induced conformational change in poliovirus: externalization of the amino terminus of VP1 is responsible for liposome binding

Open access

Abstract

Upon attachment to susceptible cells, poliovirus and a number of other picornaviruses undergo conformational transitions which result in changes in antigenicity, increased protease sensitivity, the loss of the internal capsid protein VP4, and a loss of the ability to attach to cells. These conformationally altered particles have been characterized by using a number of sequence-specific probes, including two proteases, a panel of antiviral monoclonal antibodies, and a panel of antisera against synthetic peptides which correspond to sequences from the capsid protein VP1. With these probes, cell-altered virus is clearly distinguishable from native and heat-inactivated virions. The probes also demonstrate that the cell-induced conformational change alters the accessibility of several regions of the virus. In particular, the amino terminus of VP1, which is entirely internal in the native virion, becomes externalized. Unlike native and heat-inactivated virus, cell-altered virions are able to attach to liposomes. The exposed amino terminus of VP1 is shown to be responsible for liposome attachment. We propose that during infection the amino terminus of VP1 inserts into endosomal membranes and thus plays a role in the mechanism of cell entry.

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.
