Schiestl RH and Prakash S  (1990) RAD10, an excision repair gene of Saccharomyces cerevisiae, is involved in the RAD1 pathway of mitotic recombination. Mol Cell Biol 10(6):2485-91

Abstract: The RAD10 gene of Saccharomyces cerevisiae is required for the incision step of excision repair of UV-damaged DNA. We show that the RAD10 gene is also required for mitotic recombination. The rad10 delta mutation lowered the rate of intrachromosomal recombination of a his3 duplication in which one his3 allele has a deletion at the 3' end and the other his3 allele has a deletion at the 5' end (his3 delta 3' his3 delta 5'). The rate of formation of HIS3+ recombinants in the rad10 delta mutant was not affected by the rad1 delta mutation but decreased synergistically in the presence of the rad10 delta mutation in combination with the rad52 delta mutation. These observations indicate that the RAD1 and RAD10 genes function together in a mitotic recombination pathway that is distinct from the RAD52 recombination pathway. The rad10 delta mutation also lowered the efficiency of integration of linear DNA molecules and circular plasmids into homologous genomic sequences. We suggest that the RAD1 and RAD10 gene products act in recombination after the formation of the recombinogenic substrate. The rad1 delta and rad10 delta mutations did not affect meiotic intrachromosomal recombination of the his3 delta 3' his3 delta 5' duplication or mitotic and meiotic recombination of ade2 heteroalleles located on homologous chromosomes.
