Our paper ‘Opening Pathways of the DNA Clamps Proliferating Cell Nuclear Antigen and Rad9-Rad1-Hus1’ has just been accepted by the journal Nucleic Acids Research. The recently solved structures of the DNA clamp protein 9-1-1 led to competing proposals regarding how 9-1-1 is loaded onto DNA. Through detailed subunit interface analysis, we identified the subunit interface […]
Our paper ‘Probing DNA clamps with single-molecule force spectroscopy’ has just been published in Nucleic Acids Research and sheds light on the mechanisms of DNA clamp opening under external forces by combining molecular simulation with single-molecule micromanipulation experiments.
Oak Ridge National Lab highlights our recent work on Replication Protein A:‘Neutrons help shed light on critical protein activity that protects our DNA’.
Our paper ‘A new structural framework for integrating replication protein A into DNA processing machinery’, which is currently in press in Nucleic Acids Research, has been selected as a ‘featured paper’ in the top 5% of NAR submissions.
