Function
function
Plays a role in the transcription of the viral late genes by acting as a late promoter recognition subunit. Associates with host RNA polymerase (RNAP) core and thus replaces the host sigma-70/rpoD subunit in the complex. May also play a role in DNA packaging by interacting with the terminase subunit gp17.

Interaction
Subunit
Interacts with the host RNA polymerase catalytic core formed by RpoA, RpoB, RpoC and RpoZ to form the RNAP-gp55 holoenzyme. Part of the transcription activation complex containing host RNAP, the viral RNA polymerase sigma-like factor, the late transcription coactivator, and the sliding clamp. Interacts with the terminase large subunit; this interaction may load the terminase onto DNA for packaging.
