General Information

General Information Comment Organism
physiological function RFC is an ATPase. The RFC complex from Sulfolobus solfataricus physically interacts with DNA polymerase B1 (PolB1) and enhances both the polymerase and 3'-5' exonuclease activities of PolB1 in an ATP-independent manner. Stimulation of the PolB1 activity by RFC is independent of the ability of RFC to bind DNA but is consistent with the ability of RFC to facilitate DNA binding by PolB1 through protein-protein interaction. Sulfolobus RFC may play a role in recruiting DNA polymerase for efficient primer extension, in addition to clamp loading, during DNA replication. RFC is shown to interact with the PCNA1 and PCNA2 subunits through its small subunit RFCS and with PCNA3 through its large subunit RFCL Saccharolobus solfataricus
