CC   -!- FUNCTION: Viral movemement protein which is responsible for cell-to
CC       cell spread of viral genome. Increases the size exclusion limit (SEL)
CC       of plasmodesmata by forming tubules structures, thereby allowing viral
CC       ribonucleocapsids to spread directly to neighboring cells (By
CC       similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Oligomerizes to form tubule structures through host
CC       plasmodesma. Interacts with host A.thaliana At4g26020 protein, which is
CC       involved in antra- and inter-cellular trafficking (By similarity).
CC       {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Host cell junction, host plasmodesma
CC       {ECO:0000250}. Note=Colocalizes with viral nucleocapsid aggregates in
CC       host cytoplasm.
CC   -!- SIMILARITY: Belongs to the tospovirus movement protein family.
CC       {ECO:0000305}.
