CC -!- FUNCTION: Sliding clamp subunit that acts as a moving platform for DNA
CC processing. Responsible for tethering the catalytic subunit of DNA
CC polymerase and other proteins to DNA during high-speed replication.
CC {ECO:0000256|HAMAP-Rule:MF_00317}.
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. {ECO:0000256|HAMAP-Rule:MF_00317}.
CC -!- SIMILARITY: Belongs to the PCNA family. {ECO:0000256|ARBA:ARBA00010462,
CC ECO:0000256|HAMAP-Rule:MF_00317}.
