CC   -!- FUNCTION: Self-assembles to form an icosahedral capsid with a T=1
CC       symmetry, about 30 nm in diameter, and consisting of 60 capsid
CC       proteins. The capsid encapsulates the genomic DNA. Capsid protein is
CC       involved in attachment and entry into the host cell (By similarity).
CC       {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Virion {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the anelloviridae capsid protein family.
CC       {ECO:0000305}.
