title: Protein-protein interactions during mammalian DNA single-strand break repair.
abstract: The genetic stability of living cells is continually threatened by endogenous reactive oxygen species and other genotoxic molecules. Of particular threat are the thousands of single-strand breaks that arise in each cell every day. If left unrepaired, such breaks can give rise to potentially clastogenic or lethal chromosomal double-strand breaks. This article summarizes our current understanding of how mammalian cells detect and repair single strand breaks, and provides insights into novel polypeptide components of this process.
