Reorientation of INO80 on hexasomes reveals basis for mechanistic versatility.
Science, 381:319-324, 2023

PubMed Abstract: Unlike other chromatin remodelers, INO80 preferentially mobilizes hexasomes, which can form during transcription. Why INO80 prefers hexasomes over nucleosomes remains unclear. Here, we report structures of INO80 bound to a hexasome or a nucleosome. INO80 binds the two substrates in substantially different orientations. On a hexasome, INO80 places its ATPase subunit, Ino80, at superhelical location -2 (SHL -2), in contrast to SHL -6 and SHL -7, as previously seen on nucleosomes. Our results suggest that INO80 action on hexasomes resembles action by other remodelers on nucleosomes such that Ino80 is maximally active near SHL -2. The SHL -2 position also plays a critical role for nucleosome remodeling by INO80. Overall, the mechanistic adaptations used by INO80 for preferential hexasome sliding imply that subnucleosomal particles play considerable regulatory roles.
