Title: Cryo-EM structures of the human INO80 chromatin-remodeling complex.
Authors: Ricardo J Aramayo / Oliver Willhoft / Rafael Ayala / Rohan Bythell-Douglas / Dale B Wigley / Xiaodong Zhang /
Abstract: Access to chromatin for processes such as transcription and DNA repair requires the sliding of nucleosomes along DNA. This process is aided by chromatin-remodeling complexes, such as the multisubunit ...Access to chromatin for processes such as transcription and DNA repair requires the sliding of nucleosomes along DNA. This process is aided by chromatin-remodeling complexes, such as the multisubunit INO80 chromatin-remodeling complex. Here we present cryo-EM structures of the active core complex of human INO80 at 9.6 Å, with portions at 4.1-Å resolution, and reconstructions of combinations of subunits. Together, these structures reveal the architecture of the INO80 complex, including Ino80 and actin-related proteins, which is assembled around a single RUVBL1 (Tip49a) and RUVBL2 (Tip49b) AAA+ heterohexamer. An unusual spoked-wheel structural domain of the Ino80 subunit is engulfed by this heterohexamer; both, in combination, form the core of the complex. We also identify a cleft in RUVBL1 and RUVBL2, which forms a major interaction site for partner proteins and probably communicates these interactions to its nucleotide-binding sites.

Jan 31, 2019. EMDB accession codes are about to change! (news from PDBe EMDB page)

EMDB accession codes are about to change! (news from PDBe EMDB page)

  • The allocation of 4 digits for EMDB accession codes will soon come to an end. Whilst these codes will remain in use, new EMDB accession codes will include an additional digit and will expand incrementally as the available range of codes is exhausted. The current 4-digit format prefixed with “EMD-” (i.e. EMD-XXXX) will advance to a 5-digit format (i.e. EMD-XXXXX), and so on. It is currently estimated that the 4-digit codes will be depleted around Spring 2019, at which point the 5-digit format will come into force.
  • The EM Navigator/Yorodumi systems omit the EMD- prefix.

Yorodumi

Thousand views of thousand structures

  • Yorodumi is a browser for structure data from EMDB, PDB, SASBDB, etc.
  • This page is also the successor to EM Navigator detail page, and also detail information page/front-end page for Omokage search.
  • The word "yorodu" (or yorozu) is an old Japanese word meaning "ten thousand". "mi" (miru) is to see.
