Protein
DNA polymerase processivity factor
Organism
Human herpesvirus 8 type P (isolate GK18)
Function
Plays an essential role in the viral lytic DNA replication by acting as the polymerase accessory subunit. Stimulates the viral DNA polymerase activity and appears to function with it as a holoenzyme. Increases the processivity of the viral polymerase, probably by acting as a sliding clamp that prevents dissociation of the polymerase from the active template (By similarity).
Similarity
Belongs to the herpesviridae DNA polymerase accessory subunit family.
