Nuclear actin-related proteins (Arps) are subunits of several chromatin remodelers, but their molecular functions within these complexes are unclear. We report the crystal structure of the INO80 complex subunit Arp8 in its ATP-bound form. Human Arp8 has several insertions in the conserved actin fold that explain its inability to polymerize. Most remarkably,(More)
INO80/SWR1 family chromatin remodelers are complexes composed of >15 subunits and molecular masses exceeding 1 MDa. Their important role in transcription and genome maintenance is exchanging the histone variants H2A and H2A.Z. We report the architecture of S. cerevisiae INO80 using an integrative approach of electron microscopy, crosslinking and mass(More)
