CC   -!- FUNCTION: Minor component of the viral capsid involved in aphid
CC       transmission. The RTD domain of the protein is exposed on the surface
CC       of the particle and determines the vector specificity and tropism of
CC       the virus (By similarity). The RTD domain is not necessary for virus
CC       stability in the host hemolymph. {ECO:0000250,
CC       ECO:0000269|PubMed:19240978}.
CC   -!- SUBCELLULAR LOCATION: [Minor capsid protein P3-RTD]: Virion
CC       {ECO:0000305}.
CC   -!- MISCELLANEOUS: This protein is translated as a fusion protein by
CC       episodic readthrough of the major coat protein termination codon. It is
CC       composed of the major capsid protein fused to a long C-terminal
CC       extension called the readthrough domain (RTD). Readthrough of the
CC       terminator codon TGA occurs between the codons for 189-Leu and 191-Gly.
CC   -!- MISCELLANEOUS: The N-terminal region like those of many plant virus
CC       capsid proteins is highly basic. It has been suggested that these
CC       regions may be involved in protein-RNA interaction.
CC   -!- SIMILARITY: Belongs to the luteoviruses readthrough protein family.
