CC   -!- FUNCTION: Capsid protein. Binds to the to the 3' end of the
CC       nonpolyadenylated viral RNA and is involved in viral RNA translation
CC       initiation. Probably binds RNA and plays a role in packaging (By
CC       similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Virion {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the alphamovirus/ilarvirus capsid protein
CC       family. {ECO:0000305}.
