CC -!- FUNCTION: Transports viral genome to neighboring plant cells directly
CC through plasmodesmata, without any budding. The movement protein allows
CC efficient cell to cell propagation, by bypassing the host cell wall
CC barrier. Engages in homologous interactions leading to the formation of
CC a ribonucleoprotein complex containing viral genomic and messenger RNAs
CC (vRNPs). TGBp2 and TGBp3 are necessary for intracellular delivery of
CC TGBp1-containing vRNPs to plasmodesmata (By similarity). {ECO:0000250}.
CC -!- SUBUNIT: Homooligomer. Interacts with movement protein TGB3 (By
CC similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Host cell junction, host plasmodesma
CC {ECO:0000269|PubMed:10796018, ECO:0000269|PubMed:16023167}.
CC -!- SIMILARITY: Belongs to the virgaviridae/benyvirus TGB1 movement protein
CC family. {ECO:0000305}.
