Ino80 complex subunit 5 The INO80 chromatin remodeling complex is known to be related to DNA repair in yeast, mammals, and plants. In yeast, the INO80 complex is recruited to the DSBs (DNA double-strand breaks) through the direct interaction of its Nhp10 (non-histone protein 10) or Arp4 (Actin-Related Protein) subunits with phosphorylated histone H2A. However, the ortholog of yeast Nhp10 does not exist in mammals. The Nhp10 module consists of Nhp10, Ies1, Ies3, and Ies5. These yeast-specific subunits cross-link to the N terminus of Ino80 and form a stable complex in-vitro, which helps high-affinity targeting of INO80 to nucleosome-binding.
