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. Acts by forming tubules structures that increase the size
CC       exclusion limit (SEL) of plasmodesmata, thereby allowing viral
CC       ribonucleocapsids to spread directly to neighboring cells (By
CC       similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Homotrimer, through the coiled-coil domain. Interacts with
CC       VAP. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Host cell junction, host plasmodesma
CC       {ECO:0000250}. Note=Assembles in tubules that are embedded within
CC       modified plasmodesmata.
CC   -!- SIMILARITY: Belongs to the caulimoviridae movement protein family.
CC       {ECO:0000305}.
