Publication Abstract from PubMedThe single-stranded-DNA-binding proteins (SSBs) are essential for DNA function in prokaryotic and eukaryotic cells, mitochondria, phages and viruses. The structures of four SSBs have been solved, but the molecular details of the interaction of SSBs with DNA remain speculative. We report here the crystal structure at 2.4 A resolution of the single-stranded-DNA-binding domain of human replication protein A (RPA) bound to DNA. Replication protein A is a heterotrimeric SSB that is highly conserved in eukaryotes. The largest subunit, RPA70, binds to single-stranded (ss)DNA and mediates interactions with many cellular and viral proteins.
