• 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. Acts as a linker between the capsid and tail. Required for attachment of the neck proteins to the capsid.
  subunit: Homododecamer (Probable). Part of the immature prohead complex. Might interact with viral I protease; this interaction gives rise to an early 25S initiator complex (Probable). The scaffolding protein Z and the capsid protein T should then be added to this initiator complex to yield the immature prohead (Probable). Host GroEL and GroES are also essential for the correct assembly of viral head and tail.
