The accurate repair of DNA double-strand breaks is essential for cell survival and maintenance of genome integrity. Here we describe xlf1+, a gene in the fission yeast Schizosaccharomyces pombe that is required for repair of double-strand breaks by nonhomologous end joining during G1 phase of the cell cycle. Xlf1 is the ortholog of budding yeast Nej1 and human XLF/Cernunnos proteins.
