CC   -!- FUNCTION: Capsid protein self-assembles to form an icosahedral capsid
CC       with a T=3 symmetry, about 29 nm in diameter, and consisting of 12
CC       capsid protein pentamers and 20 capsid protein hexamers. Binds to the
CC       to the 3' end of the nonpolyadenylated viral RNA and is involved in
CC       viral RNA translation initiation. Probably binds RNA and plays a role
CC       in packaging (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Virion {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the alphamovirus/ilarvirus capsid protein
CC       family. {ECO:0000305}.
