title: DNA2 resolves expanding flap in mitochondrial base excision repair.
abstract: In a recent issue of Molecular Cell, Zheng et al. (2008) demonstrated that human DNA2, originally identified in yeast as a nuclear DNA replication and repair factor, functions exclusively in mammalian mitochondria in the recently discovered long-patch base excision repair pathway.
