CC   -!- FUNCTION: Encapsidates the viral genome into characteristic twinned
CC       ('geminate') particles. Binds the genomic viral ssDNA and shuttles it
CC       into and out of the cell nucleus. Plays a role in protection of the
CC       genome from degradation, virus acquisition and transmission by insect
CC       vectors, infectivity, and systemic movement. The CP of monopartite
CC       geminiviruses is absolutely essential for virus movement (By
CC       similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Homomultimer. Interacts with the movement protein. Binds to
CC       single-stranded and double-stranded viral DNA (By similarity).
CC       {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Virion {ECO:0000250}. Host nucleus. Note=It is
CC       actively transported into the host cell nucleus. It may be exported out
CC       of the nucleus through a nuclear export signal for cell-to-cell
CC       movement and spread (By similarity). {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the geminiviridae capsid protein family.
CC       {ECO:0000305}.
