The replisome is a multiprotein machine that orchestrates duplication of the genome—including the epigenome—with strikingly high accuracy despite a constant barrage of obstacles. These challenges to replication pose risks for mutagenesis and replication fork collapse. My lab is interested in auxiliary machinery that directly couples to the core replisome, handling these obstacles in coordination with the DNA replication apparatus to achieve high fidelity chromosome duplication. Using replisomes and chromatin reconstituted from protein complexes purified in yeast, we study these molecular mechanisms in detail with single-molecule fluorescence techniques in addition to traditional biochemistry.
