Crystal structure of the RCC1-nucleosome complex (PDB: 3MVD). (a) Overview of RCC1-nucleosome complex shows that RCC1 uses loops and its N-terminal arm to engage the nucleosome. (b) RCC1 uses its switchback loop to bind to the histone dimer acidic patch and an adjacent DNA-binding loop to interact with nucleosomal DNA.
