| - | In Saccharomyces cerevisiae, four proteins, Shu1, Shu2, Psy3 and Csm2, form a stable SHU-complex both in vivo and in vitro. These proteins are involved in the early stages of the homologous recombination DNA damage repair process. In this paper, the crystal structure of the Psy3-Csm2 sub-complex is presented at 1.8A resolution and successfully fitted into our small angle X-ray scattering (SAXS) data of the SHU-complex. Taken together with our electrophoretic mobility shift assay (EMSA) results, a model is proposed for the SHU-protein complex coupled with DNA. STRUCTURED SUMMARY OF PROTEIN INTERACTIONS:: PSY3 and CSM2bind by X-ray crystallography (View interaction) PSY3, CSM2, Shu 1 and Shu 2physically interact by x ray scattering (View interaction).
