Protein
DNA polymerase processivity factor BMRF1
Organism
Epstein-Barr virus (strain AG876)
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. In addition, BMRF1 transcriptionally activates the early BHLF1 promoter (By similarity).
Similarity
Belongs to the herpesviridae DNA polymerase accessory subunit family.
