CC   -!- FUNCTION: Movement protein involved in the cell-to-cell and systemic
CC       transport of viral genomic DNA. Begomoviruses use 2 proteins to
CC       transport their DNA from cell to cell. The nuclear shuttle protein
CC       (NSP) shuttles it between nucleus and cytoplasm and the movement
CC       protein (MP) probably transports the DNA-NSP complex to the cell
CC       periphery and facilitates further movement across the cell wall (By
CC       similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Binds to dimeric supercoiled plasmid DNA. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Host cell membrane {ECO:0000250}; Peripheral
CC       membrane protein {ECO:0000250}; Cytoplasmic side {ECO:0000250}. Host
CC       microsome membrane {ECO:0000250}; Peripheral membrane protein
CC       {ECO:0000250}; Cytoplasmic side {ECO:0000250}. Host endoplasmic
CC       reticulum membrane {ECO:0000250}; Peripheral membrane protein
CC       {ECO:0000250}; Cytoplasmic side {ECO:0000250}. Note=Found on ER-derived
CC       vesicles. {ECO:0000250}.
CC   -!- PTM: Phosphorylated. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the begomovirus movement protein BC1 family.
CC       {ECO:0000305}.
