Clamp loaders such as Ctf18-RFC assist DNA replication by loading the PCNA clamp onto DNA. In this issue of Structure, Grabarczyk et al. (2018) reveal that a hook-like structure formed by the unique Dcc1 and Ctf8 subunits mediates the interaction of Ctf18-RFC with the leading strand DNA polymerase ɛ.
