CC   -!- FUNCTION: Transports viral genome to neighboring plant cells directly
CC       through plasmosdesmata, without any budding. The movement protein
CC       allows efficient cell to cell propagation, by bypassing the host cell
CC       wall barrier. Begomovirus genome is shuttled out of nucleus by Nuclear
CC       shuttle protein (NSP) and the movement protein transports the DNA-NSP
CC       complex to cell plasmodesmata and facilitates further movement across
CC       the cell wall (By 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}.
