      DNA replication is essential for an organism’s survival since the organism will die if the DNA is not replicated. The damage that DNA incurs may impede the progression of the replication process. The translesion synthesis (TLS) pathway bypasses damage, allowing replication to continue. Research conducted by our collaborator at the Augusta University Cancer Center indicates that the protein Rev1 physically interacts with Bin1, a protein involved in cancer progression in mammalian cells. We hypothesize that the two genes operate in the same pathway in yeast as they do in mammalian cells, and we intend to test this genetically. We conducted a mutation assay looking for an epistatic relationship between the two genes REV1 and HOB1, the homolog of Bin1 in Schizosaccharomyces pombe. These data suggest that Hob1 functions with Rev1 to allow for TLS, relieving stress caused by DNA damage during replication.
