CC   -!- FUNCTION: [Movement protein]: Transports viral genome to neighboring
CC       plant cells directly through plasmosdesmata, without any budding. The
CC       movement protein allows efficient cell to cell propagation, by
CC       bypassing the host cell wall barrier. Acts by forming a tubular
CC       structure at the host plasmodesmata, enlarging it enough to allow free
CC       passage of virion capsids (By similarity). {ECO:0000250}.
CC   -!- FUNCTION: Capsid proteins form a capsid enclosing the viral positive
CC       strand RNA genome. Together they form an icosahedral capsid pseudo T=3
CC       with a diameter of approximately 30 nm (Potential). {ECO:0000305}.
CC   -!- SUBCELLULAR LOCATION: [Movement protein]: Host cell junction, host
CC       plasmodesma {ECO:0000250}. Note=Assembles in tubules that are embedded
CC       within modified plasmodesmata. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: [Large capsid protein]: Virion {ECO:0000305}.
CC   -!- SUBCELLULAR LOCATION: [Small capsid protein]: Virion {ECO:0000305}.
CC   -!- PTM: Specific enzymatic cleavages by RNA1 encoded picornain 3C-like
CC       protease in vivo yield mature proteins. {ECO:0000250}.
