CC   -!- FUNCTION: Self assembles to form an icosahedral capsid, about 50 nm in
CC       diameter, nm, composed of 420 subunits of the viral capsid protein. The
CC       capsid encapsulates the genomic dsDNA. Following virus entry into host
CC       cell, provides nuclear import of the viral genome. Virus particles do
CC       not enter the nucleus, but dock at the nuclear membrane through the
CC       interaction with host importins (By similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Interacts (via nuclear localization signal) with host importin
CC       alpha. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Virion {ECO:0000305}. Host nucleus {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the caulimoviridae capsid protein family.
CC       {ECO:0000305}.
