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:0000255|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:0000255|HAMAP-Rule:MF_00317}.
CC   -!- SIMILARITY: Belongs to the PCNA family. {ECO:0000255|HAMAP-
CC       Rule:MF_00317}.
