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   -!- SIMILARITY: Belongs to the tobravirus protein 2b family. {ECO:0000305}.
