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. Binds to the terminase subunits to form the packaging machine. |
Subunit | Homododecamer. Interacts with the large terminase subunit. Interacts with the major capsid protein. Interacts with the capsid vertex protein. |
Subcellular location | Virion. Note=Located at a unique 5-fold vertex of the icosahedral capsid. |
Similarity | Belongs to the Tevenvirinae portal protein family. |
