Sister chromatid cohesion protein Dcc1 is a component of the Ctf18-RFC complex. This complex is required for the efficient establishment of chromosome cohesion during S-phase and for loading the replication clamp Pol30/PCNA, which functions in DNA replication and repair [1,2]. Ctf18-RFC loads PCNA onto DNA in an ATP-dependent manner. It may also have PCNA-unloading activity [3].
