Comments
[?]
| FUNCTION | Major capsid protein that self-associates to form hexamers, building most of the capsid in association with pentons made of the capsid vertex protein and one dodecamer of the portal protein. |
| SUBUNIT | Homohexamer. Interacts with the portal protein. Interacts with the capsid vertex protein that forms pentamers. |
| SUBCELLULAR LOCATION | Major capsid protein: Virion. Note=Part of the icosahedric capsid shell of the immature virion. |
| SIMILARITY | Belongs to the Tevenvirinae major capsid protein family. |
| case <FTTag:cleavage> | |
| SUBCELLULAR LOCATION | Major capsid protein: Virion. Note=Part of the icosahedric capsid shell of the immature virion. |
| SUBCELLULAR LOCATION | Mature major capsid protein: Virion. Note=Part of the icosahedric capsid shell of the mature virion. |
| PTM | A proteolytic cleavage by the prohead core protein protease gives rise to the mature major capsid protein during virus maturation. |
| end case | |
