    • Replication protein A (RPA), the nuclear ssDNA-binding protein in eukaryotes, is essential to DNA replication, recombination, and repair. We have shown that a globular domain at the C terminus of subunit RPA32 contains a specific surface that interacts in a similar manner with the DNA repair enzyme UNG2 and repair factors XPA and RAD52, each of which functions in a different repair pathway ...

    Replication protein A (RPA), the nuclear ssDNA-binding protein in eukaryotes, is essential to DNA replication, recombination, and repair. We have shown that a globular domain at the C terminus of subunit RPA32 contains a specific surface that interacts in a similar manner with the DNA repair enzyme UNG2 and repair factors XPA and RAD52, each of which functions in a different repair pathway. NMR structures of the RPA32 domain, free and in complex with the minimal interaction domain of UNG2, were determined, defining a common structural basis for linking RPA to the nucleotide excision, base excision, and recombinational pathways of repairing damaged DNA. Our findings support a hand-off model for the assembly and coordination of different components of the DNA repair machinery.
