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. Might act by forming tubules structures that increase the
CC       size exclusion limit (SEL) of plasmodesmata, thereby allowing viral
CC       ribonucleoproteins to spread directly to neighboring cells. Binds to
CC       ssRNA. {ECO:0000269|PubMed:11562550}.
