Movement protein

Gene

ORF3a

Organism
Cucumber mosaic virus (strain C7-2) (CMV)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

Transports viral genome to neighboring plant cells directly through plasmosdesmata, without any budding. The movement protein allows efficient cell to cell propagation, by bypassing the host cell wall barrier. Acts by forming a tubular structure at the host plasmodesmata, enlarging it enough to allow free passage of virion capsids (By similarity).By similarity
