CC   -!- FUNCTION: Major capsid protein that self-assembles to form an
CC       icosahedral capsid with a T=3 symmetry, about 23 nm in diameter, and
CC       consisting of 180 capsid proteins monomers. Most of the 180 monomers
CC       are the major capsid protein, but a small percentage contain the minor
CC       capsid protein, which has a long C-terminal extension.
CC       {ECO:0000250|UniProtKB:P17522}.
CC   -!- SUBCELLULAR LOCATION: Virion {ECO:0000250|UniProtKB:P17522}.
CC   -!- DOMAIN: The N-terminus like those of many plant virus capsid proteins
CC       is highly basic. These regions may be involved in protein-RNA
CC       interaction. {ECO:0000250|UniProtKB:P17525}.
CC   -!- SIMILARITY: Belongs to the luteoviruses capsid protein family.
CC       {ECO:0000305}.
