CC   -!- FUNCTION: Structural protein that is not essential for the viral
CC       replication either in tissue culture or in its natural host.
CC       {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Virion {ECO:0000250}.
CC   -!- MISCELLANEOUS: The gene encoding this protein is included within the N
CC       gene (alternative ORF).
CC   -!- SIMILARITY: Belongs to the coronaviruses I protein family.
CC       {ECO:0000305}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=X00990; Type=Miscellaneous discrepancy; Note=The submitted sequence has a stop codon in position 17, but this could be due to a sequencing error or to the presence of quasispecies mutations.; Evidence={ECO:0000305};
