CC   -!- FUNCTION: Minor capsid protein. {ECO:0000250|UniProtKB:Q8LTE1}.
CC   -!- SUBCELLULAR LOCATION: Virion {ECO:0000250|UniProtKB:Q8LTE1}.
CC       Note=Present in 3-10 copies per virion. The readthrough extensions are
CC       probably located on the exterior of the capsid.
CC       {ECO:0000250|UniProtKB:Q8LTE1}.
CC   -!- MISCELLANEOUS: This protein is translated as a fusion protein by
CC       episodic readthrough of the termination codon at the end of the capsid
CC       protein. Readthrough of the terminator codon occurs between the codons
CC       for Tyr-133 and Trp-134, thereby producing the readthrough extension.
CC       {ECO:0000250|UniProtKB:Q8LTE1}.
