Molecular Biology DNA Repair at the Edge

Guy Riddihough

Science, AAAS, Washington, DC 20005, USA

The nucleus of a cell can be divided into functional compartments based on transcriptional activity and DNA replication. Nagai et al. reveal a physical connection between the nuclear periphery and processes of DNA damage and repair in budding yeast. Damaged DNA, specifically collapsed replication forks and persistent double-stranded breaks, is transferred to the nuclear pores, where nuclear pore components and other proteins facilitate recombinational repair.
