CC   -!- FUNCTION: [Capsid polyprotein]: The C-terminus contains the capsid
CC       protein. The N-terminal region may act as a prohead protease.
CC       {ECO:0000269|PubMed:19010363}.
CC   -!- SUBCELLULAR LOCATION: [Capsid protein]: Virion
CC       {ECO:0000269|PubMed:19010363}.
CC   -!- PTM: The prohead protease may be autocatalytically cleaved giving rise
CC       to the mature capsid protein. {ECO:0000305|PubMed:19010363}.
