Authors: Zhenlin Yang / Amel Mameri / Claudia Cattoglio / Catherine Lachance / Alfredo Jose Florez Ariza / Jie Luo / Jonathan Humbert / Deepthi Sudarshan / Arul Banerjea / Maxime Galloy / Amélie ...Authors: Zhenlin Yang / Amel Mameri / Claudia Cattoglio / Catherine Lachance / Alfredo Jose Florez Ariza / Jie Luo / Jonathan Humbert / Deepthi Sudarshan / Arul Banerjea / Maxime Galloy / Amélie Fradet-Turcotte / Jean-Philippe Lambert / Jeff A Ranish / Jacques Côté / Eva Nogales / ![]() ![]() Abstract: The human NuA4/TIP60 co-activator complex, a fusion of the yeast SWR1 and NuA4 complexes, both incorporates the histone variant H2A.Z into nucleosomes and acetylates histones H4/H2A/H2A.Z to regulate ...The human NuA4/TIP60 co-activator complex, a fusion of the yeast SWR1 and NuA4 complexes, both incorporates the histone variant H2A.Z into nucleosomes and acetylates histones H4/H2A/H2A.Z to regulate gene expression and maintain genome stability. Our cryo-electron microscopy studies show that, within the NuA4/TIP60 complex, the EP400 subunit serves as a scaffold holding the different functional modules in specific positions, creating a unique arrangement of the ARP module. EP400 interacts with the TRRAP subunit using a footprint that overlaps with that of the SAGA acetyltransferase complex, preventing the formation of a hybrid complex. Loss of the TRRAP subunit leads to mislocalization of NuA4/TIP60, resulting in the redistribution of H2A.Z and its acetylation across the genome, emphasizing the dual functionality of NuA4/TIP60 as a single macromolecular assembly. | ||||||||||||||||||
