CC   -!- FUNCTION: Participates in the transport of viral RNA to the
CC       plasmodesmata. Is probably targeted to plasmodesmata by TGBp3, along
CC       with viral RNAs-TGBp1 (RNP complex). Can gate plasmodesmata and
CC       increase their size exclusion limit (By similarity). {ECO:0000250,
CC       ECO:0000269|PubMed:10796018}.
CC   -!- SUBUNIT: Interacts with movement protein TGB3. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Host cell junction, host plasmodesma
CC       {ECO:0000305}. Host endoplasmic reticulum membrane {ECO:0000305};
CC       Multi-pass membrane protein {ECO:0000305}. Note=localizes to
CC       plasmodesmata or plasmodesmata-associated membrane compartments called
CC       peripheral membrane bodies (PMBs). {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the virgaviridae/benyvirus TGB2 movement protein
CC       family. {ECO:0000305}.
