Human replication protein A (RPA) is a single-stranded DNA (ssDNA) binding protein complex required for DNA replication, recombination, and repair. RPA is a stable heterotrimer consisting of subunits with molecular masses of 14, 32 and 70 kDa (p14, p32 and p70, respectively). Association of RPA with ssDNA is thought to contribute to both the protection and removal of secondary structure from single-stranded DNA (ssDNA) (McIlwraith et al. 2000). The RPA complexes coat 3'-ssDNA overhangs generated by RBBP8 (CtIP)-initiated long-range resection of DNA double strand breaks (DSBs) (Sartori et al. 2007, Chen et al. 2008).
