CC -!- FUNCTION: Plays a role in viral cell-to-cell propagation, by
CC facilitating genome transport to neighboring plant cells through
CC plasmosdesmata. May induce the formation of granular vesicles derived
CC from the Endoplasmic reticulum, which align on actin filaments (By
CC similarity). {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 TGBp3 protein family.
CC {ECO:0000305}.
