Movement protein TGB2

Gene

ORF3

Organism
Papaya mosaic potexvirus (PMV)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

Plays a role in viral cell-to-cell propagation, by facilitating genome transport to neighboring plant cells through plasmosdesmata,.By similarity

Miscellaneous

TGBp1, TGBp2 and TGBp3 seem to act together for cell-to-cell propagation. TGBp1 is the main movement protein that physically cross the plasmodesma with the viral genome. TGBp2 and TGBp3 would facilitate TGBp1 function.
