Za elongaciju prajmiranog DNK šablona DNK polimeraze delta i DNK polimeraze epsilon neophodni su pomoćni proteini: proliferativni ćelijski nuklearni antigen (PCNA) i replikacioni faktor C (RFC). RFC, takođe poznat kao aktivator 1, je proteinski kompleks koji se sastoji od pet podjedinica sa 140, 40, 38, 37, i 36 kDa. Ova podjedinica formira sržni kompleks sa 36 i 40 kDa podjedinicama. Kompleks manifestuje DNK zavisno ATPazno dejstvo, koje može da stimuliše PCNA u in vitro sistemima. Poznate su alternativno splajsovane transcriptne varijante koje kodiraju različite izoforme.[2]
