During the transition from pre-replicative complexes to pre-initiation complexes, MCM10 recruitment to replication origins is required to provide a physical link between the MCM2-7 complex DNA helicase and DNA polymerases. Here, we report the molecular structure of human MCM10 as determined by electron microscopy and single-particle analysis. The MCM10 molecule is a ring-shaped hexamer with large central and smaller lateral channels and a system of inner chambers. This structure, together with biochemical data, suggests that this important protein uses its architecture to provide a docking module for assembly of the molecular machinery required for eukaryotic DNA replication. |
