Abstract

The mouse lymphoma (L5178Y) cell mutant M10 is defective in rejoining DNA double-strand breaks and is hypersensitive to ionizing radiation. The introduction of human chromosome 5 into M10 cells by microcell mediated chromosome transfer complemented the ionizing-radiation hypersensitivity defect of this cell line. The presence of chromosome 5 in the microcell hybrids was shown using PCR with chromosome-specific primers and fluorescence in situ hybridization. From this data we conclude that the gene that corrects the radiation hypersensitivity of M10 cells is located on chromosome 5 and tentatively assigned to the 5q14 to 5pter region. We designate this gene XRCC4L.
