Protein Structure
UniProt Annotation
Function Chromosome cohesion factor involved in sister chromatid cohesion and fidelity of chromosome transmission. Component of one of the cell nuclear antigen loader complexes, CTF18-replication factor C (CTF18-RFC), which consists of CTF18, CTF8, DCC1, RFC2, RFC3, RFC4 and RFC5. The CTF18-RFC complex binds to single- stranded and primed DNAs and has weak ATPase activity that is stimulated by the presence of primed DNA, replication protein A (RPA) and by proliferating cell nuclear antigen (PCNA). The CTF18- RFC complex catalyzes the ATP-dependent loading of PCNA onto primed and gapped DNA. It also interacts with and stimulates DNA polymerase POLH. {ECO:0000269PubMed:12766176, ECO:0000269PubMed:12930902, ECO:0000269PubMed:17545166}.
Subcellular Localization Nucleus {ECO:0000269PubMed:12766176}. Note=Associates with chromatin during S phase.
