Recombinant Mengo encephalomyocarditis virus Genome polyprotein

Forms a complex with host RAN and probably binds to exportins carrying activated MAPK in order to mediate the hyperphosphorylation of host Phe/Gly containing nuclear pore proteins (Nups) resulting in cessation of active nucleocytoplasmic transport. Proteins with NLS signals fail to import, cellular mRNAs fail to export, and some proteins small enough for diffusion are not retained anymore (efflux). The resulting inhibition of cellular protein synthesis serves to ensure maximal viral gene expression and to evade host immune response.; Forms an icosahedral capsid of pseudo T=3 symmetry with capsid proteins VP2 and VP3. Together they form an icosahedral capsid composed of 60 copies of each VP1, VP2, and VP3, with a diameter of approximately 300 Angstroms.VP4 lies on the inner surface of the protein shell formed by VP1, VP2 and VP3. All the three latter proteins contain a beta-sheet structure called beta-barrel jelly roll. VP1 is situated at the 12 fivefold axes, whereas VP2 and VP3 are located at the quasi-sixfold axes.; Forms an icosahedral capsid of pseudo T=3 symmetry with capsid proteins VP2 and VP3.

After binding to the host receptor, the capsid undergoes conformational changes. Capsid protein VP4 is released, capsid protein VP1 N-terminus is externalized, and together, they shape a pore in the host membrane through which the viral genome is translocated into the host cell cytoplasm. After genome has been released, the channel shrinks.; VP0 precursor is a component of immature procapsids.
