CC   -!- FUNCTION: Decoration protein that binds to each capsid protein hexamer
CC       after capsid expansion and forms spikes at the surface of the capsid.
CC       Each of the 60 hexamers has three copies of the decoration protein gp12
CC       in its center. {ECO:0000269|PubMed:22514336}.
CC   -!- SUBUNIT: Interacts with the capsid protein gp13.
CC       {ECO:0000269|PubMed:22514336}.
CC   -!- SUBCELLULAR LOCATION: Virion {ECO:0000269|PubMed:22514336}. Note=180
CC       copies of the decoration protein are localized on the exterior of the
CC       capsid. {ECO:0000269|PubMed:22514336}.
