The single-stranded DNA binding (SSB) proteins play essential roles in the repair of many types of DNA damage, including double-stranded breaks (DSBs). Double-strand breaks (DSBs) are one of the severest types of DNA damage. The single-stranded binding protein is also important to maintain genome stability, since unrepaired DSBs easily induce cell death or chromosome aberrations. To maintain genome instability, cells have developed a cell-intrinsic network mechanism called DNA Damage Response

In this perspective, we will describe how single-stranded DNA binding proteins functions during the DSB repair pathway and their consequences for genome stability and cancer.
