Abstract
Single-stranded DNA-binding proteins (SSBs) play essential roles in DNA replication, recombinational repair, and maintenance of genome stability. In human, the major SSB, replication protein A (RPA), is a stable heterotrimer composed of subunits of RPA1, RPA2, and RPA3, each of which is conserved not only in mammals but also in all other eukaryotic species. In addition to RPA, other SSBs have also been identified in the human genome, including sensor of single-stranded DNA complexes 1 and 2 (SOSS1/2). In this review, we summarize our current understanding of how these SSBs contribute to the maintenance of genome stability.Entities:
