CC -!- FUNCTION: Capsid protein self-assembles to form rod-shaped virions
CC about 20 nm in diameter with a central canal enclosing the viral
CC genomic RNA. Isoform N-CP does not seem to be required for virion
CC formation and systemic infection in host plant.
CC {ECO:0000269|PubMed:11062037}.
CC -!- SUBCELLULAR LOCATION: Virion {ECO:0000305}.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative initiation; Named isoforms=2;
CC Name=Capsid protein;
CC IsoId=Q06388-1; Sequence=Displayed;
CC Name=N-CP; Synonyms=24-kDa extended protein;
CC IsoId=Q06388-2; Sequence=VSP_041680;
CC -!- MISCELLANEOUS: [Isoform N-CP]: Translationally initiated at a CTG codon
CC 120 nucleotides upstream of the ATG initiation codon for the CP gene.
CC {ECO:0000305}.
CC -!- SIMILARITY: Belongs to the virgaviridae capsid protein family.
CC {ECO:0000305}.
