Comments
[?]
| FUNCTION | Forms the portal vertex of the capsid. This portal plays critical roles in head assembly, genome packaging, neck/tail attachment, and genome ejection. The portal protein multimerizes as a single ring-shaped homododecamer arranged around a central channel. |
| SUBUNIT | Homododecamer. Interacts with major capsid protein. Interacts with the tail tube protein gp11. Interacts with the terminase large subunit. Interacts with the internal virion protein gp14. |
| SUBCELLULAR LOCATION | Virion. |
| SIMILARITY | Belongs to the podoviridae portal protein family. |
