CC -!- FUNCTION: One of the sliding clamp subunits that acts as a moving
CC platform for DNA processing. Responsible for tethering the catalytic
CC subunit of DNA polymerase to DNA during high-speed replication.
CC Heterotrimer stimulates the Holliday junction resolvase Hjc. DNA
CC polymerase I, DNA ligase and the flap endonuclease may be
CC constitutively associated with the PCNA heterotrimer forming a scanning
CC complex able to couple DNA synthesis and Okazaki fragment maturation.
CC {ECO:0000269|PubMed:17011573}.
CC -!- SUBUNIT: Forms homodimers with PCNA1, which then recruit PCNA3; does
CC not form homotrimers (PubMed:12535540, PubMed:18703842). The
CC heterodimers interact with RfcS homotetramers (PubMed:12535540).
CC Heterotrimer which circularizes head-to-tail (head is at N-terminus,
CC tail is at C-terminus) to form a toroid; DNA passes through its center.
CC Replication factor C (RFC) is required to load the toroid on the DNA.
CC This subunit interacts with DNA polymerase I (dpo1) (PubMed:12535540).
CC The heterotrimer also interacts with flap endonuclease 1, DNA ligase
CC and XPF via the other subunits. {ECO:0000269|PubMed:12535540,
CC ECO:0000269|PubMed:12675797, ECO:0000269|PubMed:16945955,

CC ECO:0000269|PubMed:19054331}.
CC -!- SIMILARITY: Belongs to the PCNA family. {ECO:0000255|HAMAP-
CC Rule:MF_00317}.
CC -!- SEQUENCE CAUTION:
CC Sequence=AAK41309.1; Type=Erroneous initiation; Note=Extended N-terminus.; Evidence={ECO:0000305};
