Responsible for tethering the catalytic subunit of DNA CC polymerase and other proteins to DNA during high-speed replication. CC -!- SUBUNIT: Homotrimer. The subunits circularize to form a toroid; DNA CC passes through its center. Replication factor C (RFC) is required to CC load the toroid on the DNA. CC -!- SIMILARITY: Belongs to the PCNA family.
