AB - Access to DNA within nucleosomes is required for a variety of processes in cells including transcription, replication and repair. Consequently, cells encode multiple systems that remodel nucleosomes. These complexes can be simple, involving one or a few protein subunits, or more complicated multi-subunit machines1. Biochemical studies2-4 have placed the motor domains of several remodellers on the superhelical location (SHL) 2 region of the nucleosome. Structural studies on Chd1 and Snf2 (RSC) in complex with nucleosomes5-7 have provided insights into the basic mechanism of nucleosome sliding by these complexes. However, how larger, multi-subunit remodelling complexes, such as INO80, interact with nucleosomes or how remodellers carry out functions such as nucleosome sliding8, histone exchange9, and nucleosome spacing10-12 remains poorly understood. Although some remodellers work as monomers13, others work as highly cooperative dimers11,14,15. Here we present the structure of the INO80 chromatin remodeller with a bound nucleosome revealing that INO80 interacts with nucleosomes in a unique manner with the motor domains located at the entry point to the wrap around the histone core rather than at SHL2. The Arp5-Ies6 module of INO80 makes additional contacts on the opposite side of the nucleosome. This unique arrangement allows the H3 tails of the nucleosome to play a role in regulation, differing from other characterised remodellers.
