Conformational distortions induced by periodically recurring A…A in d(CAG).d(CAG) provide stereochemical rationale for the trapping of MSH2.MSH3 in polyQ disorders
CAG repeat instability causes a number of neurodegenerative disorders. The unusual hairpin stem structure formed by the CAG repeats in DNA traps the human mismatch repair MSH2.MSH3 (Mutsβ) complex. To understand the mechanism behind the abnormal binding of Mutsβ with the imperfect hairpin stem struc...
