Abstract

Holliday junction D-loops branch migration DNA strand exchange Homologous recombination joint molecules
Double-stranded DNA breaks (DSB), the most harmful type of DNA lesions, cause cell death and genome instability. Homologous recombination repairs DSB using homologous DNA sequences as templates. Here we describe a set of reactions that lead to reconstitution of the double-stranded DNA break repair process in vitro employing purified human homologous recombination proteins and DNA polymerase η. Reconstitution of critical steps of DSB repair in vitro may help to better understand the mechanisms of recombinational DNA repair and the role of various human homologous recombination proteins in this process.
