To maintain the nucleosome organization of transcribed genes, ATP-dependent chromatin remodelers collaborate with histone chaperones. Here, we show that at the 5' ends of yeast genes, RNA polymerase II (RNAPII) generates hexasomes that occur directly adjacent to nucleosomes. The resulting hexasome-nucleosome complexes are then resolved by Chd1. We present two cryoelectron microscopy (cryo-EM) structures of Chd1 bound to a hexasome-nucleosome complex before and after restoration of the missing inner H2A/H2B dimer by FACT. Chd1 uniquely interacts with the complex, positioning its ATPase domain to shift the hexasome away from the nucleosome. In the absence of the inner H2A/H2B dimer, its DNA-binding domain (DBD) packs against the ATPase domain, suggesting an inhibited state. Restoration of the dimer by FACT triggers a rearrangement that displaces the DBD and stimulates Chd1 remodeling. Our results demonstrate how chromatin remodelers interact with a complex nucleosome assembly and suggest how Chd1 and FACT jointly support transcription by RNAPII. 履歴 登録 2024年8月4日 - ヘッダ(付随情報) 公開 2024年9月18日 - マップ公開 2024年9月18日 - 更新 2024年10月2日 - 現状 2024年10月2日 処理サイト : PDBe / 状態 : 公開
