CC   -!- FUNCTION: May function by interacting with a small, flexible domain
CC       located at the C-terminus of the CP, forming a bridge between the virus
CC       particle and the internal surface of the vector nematode feeding
CC       apparatus.
CC   -!- SUBCELLULAR LOCATION: Virion {ECO:0000269|PubMed:12202212}.
CC   -!- MISCELLANEOUS: The genome of this virus consists of two linear,
CC       positive, single-stranded RNAs encapsidated in separate virions. They
CC       are designated RNA-1 and RNA-2.
CC   -!- MISCELLANEOUS: This protein was translated from the RNA-2.
CC   -!- SIMILARITY: Belongs to the tobravirus protein 2b family. {ECO:0000305}.
