Eukaryotic replication initiation is highly regulated and dynamic. It begins with the origin recognition complex (ORC) binding DNA sites called origins of replication. ORC, together with Cdc6 and Cdt1, mediate pre-replicative complex (pre-RC) assembly by loading a double hexamer of Mcm2–7: the core of the replicative helicase. Here, we use single-molecule imaging to directly visualize Saccharomyces...
Loading of the ring-shaped Mcm2–7 replicative helicase around DNA licenses eukaryotic origins of replication. During loading, Cdc6, Cdt1, and the origin-recognition complex (ORC) assemble two heterohexameric Mcm2–7 complexes into a head-to-head double hexamer that facilitates bidirectional replication initiation. Using multi-wavelength single-molecule fluorescence to monitor the events of helicase...
Viral hijacking of cellular processes relies on the ability to mimic the structure or function of cellular proteins. Many viruses encode ubiquitin ligases to facilitate infection, although the mechanisms by which they select their substrates are often unknown. The Herpes Simplex Virus type-1-encoded E3 ubiquitin ligase, ICP0, promotes infection through degradation of cellular proteins, including the...
