Function | Assembles with the major capsid protein to form an icosahedral capsid. The major and minor capsid proteins are incorporated into the capsid in about a 90/10 ratio respectively. Once the capsid is formed, encapsidates one single copy of the viral genome. |
Subunit | Interacts with the connector protein and the major capsid protein. |
Subcellular location | Virion. |
Miscellaneous | The minor capsid protein is produced by a -1 ribosomal frameshift near the C-terminus of the ORF coding for the major capsid protein, producing a protein with a C-terminal extension compared to the major capsid protein. The major capsid protein is produced by conventional translation of the same ORF. |
Similarity | Belongs to the T7virus minor capsid protein family. |

Subunit | Homohexamer. Interacts with the connector protein and the minor capsid protein. Interacts with the capsid assembly scaffolding protein; capsid proteins and scaffolding proteins form building blocks that assemble to form the procapsid, each hexamer of the major capsid protein interacting with 2 scaffolding proteins. |
Domain | The N-terminus interacts with an internal region of the major capsid protein subunit in an adjacent capsomere (intercapsomeric interactions) to stabilize the capsid. |
Subcellular location | Virion. |
Similarity | Belongs to the T7virus major capsid protein family. |
