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 a tubular structure at the host
CC       plasmodesmata, enlarging it enough to allow free passage of virion
CC       capsids (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Host cell junction, host plasmodesma
CC       {ECO:0000250}. Note=Assembles into long tubular structures at the
CC       surface of the infected protoplast. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the cucumovirus movement protein family.
CC       {ECO:0000305}.
