Interdomain communication of the Chd1 chromatin remodeler across the DNA gyres of the nucleosome. INO80 exchanges H2A.Z for H2A by translocating on DNA proximal to histone dimers. Architecture of the SWI/SNF-nucleosome complex. The biology of chromatin remodeling complexes. This arrangement enables the histone H3 tails of the nucleosome to have a role in the regulation of the activities of the INO80 motor domain-unlike in other characterized remodellers, for which H4 tails have been shown to regulate the motor domains.Ĭlapier, C. The ARP5–IES6 module of INO80 makes additional contacts on the opposite side of the nucleosome. Here we present the structure of the human INO80 chromatin remodeller with a bound nucleosome, which reveals that INO80 interacts with nucleosomes in a previously undescribed manner: the motor domains are located on the DNA at the entry point to the nucleosome, rather than at superhelical location 2. Although some remodellers work as monomers 13, others work as highly cooperative dimers 11, 14, 15. However, how larger, multi-subunit remodelling complexes such as INO80 interact with nucleosomes and how remodellers carry out functions such as nucleosome sliding 8, histone exchange 9 and nucleosome spacing 10, 11, 12 remain poorly understood. Structural studies of yeast Chd1 and Snf2-a subunit in the complex with the capacity to remodel the structure of chromatin (RSC)-in complex with nucleosomes 5, 6, 7 have provided insights into the basic mechanism of nucleosome sliding performed by these complexes. ![]() Biochemical studies 2, 3, 4 have placed the motor domains of several chromatin remodellers in the superhelical location 2 region of the nucleosome. These complexes can be simple, involving one or a few protein subunits, or more complicated multi-subunit machines 1. Consequently, cells encode multiple systems that remodel nucleosomes.
