Chromosome transmission fidelity protein 8 homolog (CHTF8)

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 variable C (CTF18-RFC), which is made up 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 the presence of primed DNA, replication protein A (RPA) and proliferating cell nuclear antigen (PCNA). The CTF18-RFC complex catalyzes the ATP-dependent loading of PCNA onto primed and gapped DNA.
