The N-terminal half of RAD52 is primarily responsible for self-oligomerisation and DNA binding. Crystallographic studies have revealed the detailed structure of the N-terminal half. However, only low-resolution structures have been reported for the full-length protein, and thus the structural role of the C-terminal half in self-oligomerisation has remained elusive. In this study, we determined the solution structure of the human RAD52 protein by cryo-electron microscopy (cryo-EM), at an average resolution of 3.5 Å. The structure revealed an undecameric ring that is nearly identical to the crystal structures of the N-terminal half. The cryo-EM map for the C-terminal half was poorly defined, indicating that the region is intrinsically disordered. The present cryo-EM structure provides important insights into the mechanistic roles played by the N-terminal and C-terminal halves of RAD52 during DNA double-strand break repair. |
