CC   -!- FUNCTION: Component that constitutes the body part of the virion. Also
CC       acts as a movement protein that is involved in local cell-cell movement
CC       via plamodesmata. At least five viral proteins, CP, CPm, p6, p64 and
CC       Hsp70h are essential for cell-cell movement.
CC       {ECO:0000269|PubMed:11742977}.
CC   -!- SUBCELLULAR LOCATION: Virion.
CC   -!- SIMILARITY: Belongs to the closteroviridae capsid protein family.
CC       {ECO:0000305}.
