CC   -!- FUNCTION: Required for genome encapsidation. Forms ribonucleoprotein
CC       complexes along with TGB1 helicase and viral RNA.
CC   -!- SUBCELLULAR LOCATION: Virion {ECO:0000305}.
CC   -!- MISCELLANEOUS: The N- and the C-terminus of this capsid protein may be
CC       exposed on the surface of the virus particle. The central core sequence
CC       may be important in maintaining correct tertiary structure of the
CC       capsid protein and/or play a role in interacting with the viral RNA.
CC   -!- SIMILARITY: Belongs to the potexviruses coat protein family.
CC       {ECO:0000305}.
