DNA-translocation-independent role of INO80 remodeler in DNA damage repairs.
Title: DNA-translocation-independent role of INO80 remodeler in DNA damage repairs.
Arp8 engages N-actin in a manner distinct from that of other actin-fold proteins and thereby specifies recruitment of the Arp4-N-actin heterodimer to a segmented scaffold of the helicase-SANT-associated (HSA) domain of Ino80
Title: The nuclear actin-containing Arp8 module is a linker DNA sensor driving INO80 chromatin remodeling.
Binding of INO80 to these genes is cell cycle regulated, with a maximum binding preceding their transcription and accumulation of their mRNAs. In fact, the INO80 complex is required to fully and timely activate the transcription of these genes
Title: The INO80 complex activates the transcription of S-phase genes in a cell cycle-regulated manner.
we report that Isw2 and Ino80 promote efficient firing of the ribosomal origin of replication and facilitate the regulated increase of rDNA repeat copy number. This work significantly expands our understanding of the importance of ATP-dependent chromatin remodeling for rDNA biology.
Title: Chromatin Remodeling Factors Isw2 and Ino80 Regulate Chromatin, Replication, and Copy Number of the Saccharomyces cerevisiae Ribosomal DNA Locus.
indicate that INO80 is a highly processive remodeling motor that is tightly regulated by both substrate cues and non-catalytic subunits
Title: The Yeast INO80 Complex Operates as a Tunable DNA Length-Sensitive Switch to Regulate Nucleosome Sliding.
INO80 translocates along DNA at the H2A-H2B interface of nucleosomes and persistently displaces DNA from the surface of H2A-H2B. The data suggest that INO80 has a mechanism for dimer exchange that is distinct from other chromatin remodellers including its paralogue SWR1.
Title: INO80 exchanges H2A.Z for H2A by translocating on DNA proximal to histone dimers.
The INO80 complex is a central component of metabolic homeostasis that influences histone acetylation and may contribute to disease when disrupted.
Title: The INO80 chromatin remodeler sustains metabolic stability by promoting TOR signaling and regulating histone acetylation.
results demonstrate the chaperone-like potential of Rvb1/Rvb2 and suggest a model where binding of multiple clients such as Ino80 stimulates ATP-driven cycling between hexamers and dodecamers, providing iterative opportunities for correct subunit assembly.
