CC   -!- FUNCTION: Capsid protein self-assembles to form rod-shaped virions
CC       about 21,6 nm in diameter for the narrow nes and 22,4 for the wide
CC       ones, and 110-150 nm in length depending on the size of the
CC       encapsidated RNA (PubMed:23725818, PubMed:26278173). They display a
CC       helical symmetry of 23.2 subunits per turn of the viral helix and with
CC       a central canal enclosing the viral genomic RNA (PubMed:23725818).
CC       {ECO:0000269|PubMed:23725818, ECO:0000269|PubMed:26278173}.
CC   -!- SUBUNIT: Interacts with itself. {ECO:0000269|PubMed:23725818,
CC       ECO:0000269|PubMed:26278173}.
CC   -!- INTERACTION:
CC       P04866; P04866: -; NbExp=2; IntAct=EBI-16170091, EBI-16170091;
CC   -!- SUBCELLULAR LOCATION: Virion {ECO:0000269|PubMed:23725818,
CC       ECO:0000269|PubMed:26278173}.
CC   -!- MISCELLANEOUS: The genome of this virus consists of three linear,
CC       positive, single-stranded RNAs encapsidated in separate virions
CC       designated RNA-alpha, RNA-beta and RNA-gamma. Three proteins (alpha-A,
CC       beta-A and gamma-A) are translated directly from these genomic RNAs and
CC       the remaining proteins encoded on RNA-beta (beta-B, beta-C and beta-D)
CC       and RNA-gamma (gamma-B) are expressed via three subgenomic messenger
CC       RNAs. {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the virgaviridae capsid protein family.
CC       {ECO:0000305}.
