CC -!- FUNCTION: Together with movement protein P3a, facilitates long-distance
CC movement of virions in host (By similarity). Transports viral genome to
CC neighboring plant cells directly through plasmosdesmata, without any
CC budding (Probable). The movement protein allows efficient cell to cell
CC propagation, by bypassing the host cell wall barrier (Probable). Binds
CC ssRNA (By similarity). {ECO:0000250|UniProtKB:P10471,
CC ECO:0000250|UniProtKB:P17524, ECO:0000305}.
CC -!- SUBUNIT: Homodimer. {ECO:0000250|UniProtKB:P10471}.
CC -!- SUBCELLULAR LOCATION: Host cell junction, host plasmodesma
CC {ECO:0000250|UniProtKB:P09511}. Host Golgi apparatus
CC {ECO:0000250|UniProtKB:P09511}.
CC -!- DOMAIN: The N-terminus is involved in homodimerization (By similarity).
CC The C-terminus binds ssRNA (By similarity). The C-terminus is
CC phosphorylated (By similarity). {ECO:0000250|UniProtKB:P10471}.
CC -!- PTM: Phosphorylated. {ECO:0000250|UniProtKB:P10471}.
CC -!- MISCELLANEOUS: Poleroviruses are transmitted by aphids directly into
CC phloem tissue. The virus replicates most efficiently in phloem
CC companion cells and then moves through plasmodesmata between companion
CC cells or into sieve elements for long distance transport.
CC {ECO:0000305}.
CC -!- SIMILARITY: Belongs to the polerovirus movement protein family.
CC {ECO:0000305}.
