CC   -!- FUNCTION: Participates in the transport of viral genome to neighboring
CC       plant cells directly through plasmodesmata, without any budding. TGBp2
CC       and TGBp3 are necessary for intracellular delivery of TGBp1-containing
CC       vRNPs to plasmodesmata. Can gate plasmodesmata and increase their size
CC       exclusion limit. Induces host actin cytoskeleton network thickening,
CC       which probably plays a major role in virus cell-to-cell movement.
CC       {ECO:0000250|UniProtKB:P04868}.
CC   -!- SUBUNIT: Interacts with movement proteins TGB1 and TGB2. TGB1-TGB3-TGB2
CC       complex formation is enhanced by ATP hydrolysis.
CC       {ECO:0000250|UniProtKB:P04868}.
CC   -!- SUBCELLULAR LOCATION: Host cell junction, host plasmodesma
CC       {ECO:0000250|UniProtKB:P04868}. Host endoplasmic reticulum membrane
CC       {ECO:0000250|UniProtKB:P04868}; Multi-pass membrane protein
CC       {ECO:0000250|UniProtKB:Q9IV52}. Host cytoplasm, host cytoskeleton
CC       {ECO:0000250|UniProtKB:P04868}. Note=Probably localizes to
CC       plasmodesmata-associated membrane compartments called peripheral
CC       membrane bodies (PMBs). Associates with host actin filaments.
CC       {ECO:0000250|UniProtKB:P04868}.
CC   -!- DOMAIN: The 2nd transmembrane domain is involved in plasmodesmata
CC       targeting. {ECO:0000250|UniProtKB:Q9IV52}.
CC   -!- SIMILARITY: Belongs to the virgaviridae TGB3 movement protein family.
CC       {ECO:0000305}.
