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}.
