The roles of chromatin remodelling factors in replication.
Dynamic changes of chromatin structure control DNA-dependent events, including DNA replication. Along with DNA, chromatin organization must be replicated to maintain genetic and epigenetic information through cell generations. Chromatin remodelling is important for several steps in replication: determination and activation of origins of replication, replication machinery progression, chromatin assembly and DNA repair. Histone chaperones such as the FACT complex assist DNA replication within chromatin, probably by facilitating both nucleosome disassembly and reassembly. ATP-dependent nucleosome remodelling enzymes of the SWI/SNF family, in particular imitation switch (ISWI)-containing complexes, have been linked to DNA and chromatin replication. They are targeted to replication sites to facilitate DNA replication and subsequent chromatin assembly.
