CC   -!- FUNCTION: Assembles with the major capsid protein to form an
CC       icosahedral capsid. The major and minor capsid proteins are
CC       incorporated into the capsid in about a 90/10 ratio respectively. Once
CC       the capsid is formed, encapsidates one single copy of the viral genome.
CC   -!- SUBUNIT: Interacts with the connector protein and the major capsid
CC       protein.
CC   -!- SUBCELLULAR LOCATION: Virion.
CC   -!- MISCELLANEOUS: The minor capsid protein is produced by a -1 ribosomal
CC       frameshift near the C-terminus of the ORF coding for the major capsid
CC       protein, producing a protein with a C-terminal extension compared to
CC       the major capsid protein. The major capsid protein is produced by
CC       conventional translation of the same ORF.
CC   -!- SIMILARITY: Belongs to the T7virus minor capsid protein family.

CC   -!- SUBUNIT: Homohexamer. Interacts with the connector protein and the
CC       minor capsid protein. Interacts with the capsid assembly scaffolding
CC       protein; capsid proteins and scaffolding proteins form building blocks
CC       that assemble to form the procapsid, each hexamer of the major capsid
CC       protein interacting with 2 scaffolding proteins.
CC   -!- DOMAIN: The N-terminus interacts with an internal region of the major
CC       capsid protein subunit in an adjacent capsomere (intercapsomeric
CC       interactions) to stabilize the capsid.
CC   -!- SUBCELLULAR LOCATION: Virion.
CC   -!- SIMILARITY: Belongs to the T7virus major capsid protein family.
