== Function ==

[https://www.uniprot.org/uniprot/RFC1_YEAST RFC1_YEAST] Component of the ATP-dependent clamp loader RFC complex for the POL30/PCNA homotrimer DNA clamp. During a clamp loading circle, the RFC:clamp complex binds to DNA and the recognition of the double-stranded/single-stranded junction stimulates ATP hydrolysis by RFC. The complex presumably provides bipartite ATP sites in which one subunit supplies a catalytic site for hydrolysis of ATP bound to the neighboring subunit. Dissociation of RFC from the clamp leaves the clamp encircling DNA. Replication factor C (RFC or activator 1) complex acts during elongation of primed DNA templates by DNA polymerase delta and epsilon. RFC has an essential but redundant activity in sister chromatid cohesion establishment.
