CC   -!- FUNCTION: Plays a role in viral cell-to-cell propagation, by
CC       facilitating genome transport to neighboring plant cells through
CC       plasmosdesmata,. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Host endoplasmic reticulum membrane
CC       {ECO:0000250}.
CC   -!- MISCELLANEOUS: TGBp1, TGBp2 and TGBp3 seem to act together for cell-to-
CC       cell propagation. TGBp1 is the main movement protein that physically
CC       cross the plasmodesma with the viral genome. TGBp2 and TGBp3 would
CC       facilitate TGBp1 function.
CC   -!- SIMILARITY: Belongs to the Tymovirales TGBp2 protein family.
CC       {ECO:0000305}.
