CC   -!- FUNCTION: Encapsidates the viral DNA into characteristic twinned
CC       ('geminate') particles. Binds the genomic viral ssDNA and shuttles it
CC       into and out of the cell nucleus. The CP of bipartite geminiviruses is
CC       not required for cell-to-cell or systemic movement.
CC   -!- SUBUNIT: Homomultimer. Binds to single-stranded and double-stranded
CC       viral DNA. Interacts (via nuclear localization signals) with host
CC       importin alpha-1a (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Virion {ECO:0000305}. Host nucleus {ECO:0000250}.
CC       Note=It is actively transported into the host cell nucleus. It may be
CC       exported out of the nucleus through a nuclear export signal for cell-
CC       to-cell movement and spread (By similarity). {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the geminiviridae capsid protein family.
CC       {ECO:0000305}.
