| + | [https://www.uniprot.org/uniprot/PCNA1_SACS2 PCNA1_SACS2] One of the sliding clamp subunits that acts as a moving platform for DNA processing. Responsible for tethering the catalytic subunit of DNA polymerase to DNA during high-speed replication. Heterotrimer stimulates the Holliday junction resolvase Hjc. DNA polymerase I, DNA ligase and the flap endonuclease may be constitutively associated with the PCNA heterotrimer forming a scanning complex able to couple DNA synthesis and Okazaki fragment maturation.<ref>PMID:12535540</ref> <ref>PMID:17011573</ref> | ||
