CC   -!- FUNCTION: Capsid protein. Probably binds RNA and plays a role in
CC       packaging (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Virion {ECO:0000305}.
CC   -!- DOMAIN: The N-terminal arginine-rich stretch does not seem to be the
CC       major RNA-binding region that allows formation of an infectious
CC       ribonucleoprotein complex. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the cucumovirus capsid protein family.
CC       {ECO:0000305}.
