Title: In-situ cryo-ET of mouse embryos reveals cytoplasmic lattices contain ubiquitin-charged E2-E3 ligase assemblies.
Authors: Kashish Singh / Katarina Harasimov / Kathy K Niakan / Andrew P Carter /
Abstract: Cytoplasmic lattices (CPLs) are filamentous assemblies essential for mammalian embryonic development. They are known to regulate organelle organization, spindle assembly, and protein homeostasis, but ...Cytoplasmic lattices (CPLs) are filamentous assemblies essential for mammalian embryonic development. They are known to regulate organelle organization, spindle assembly, and protein homeostasis, but their molecular functions remain unclear. Here, we develop a strategy combining cryo-focused ion beam milling and cryo-electron tomography to resolve macromolecular complexes directly in mammalian embryos. Using this approach, we determine the in situ structure of cytoplasmic lattices within 6/8-cell mouse embryos at ~4.7 Å resolution. CPL filaments are built from multiple copies of at least fourteen proteins arranged into a ~4.5 MDa repeating unit. The repeat contains a central cavity that is open at the back and lined with multiple FBXW-SKP1 complexes and three modules, each containing the E2 ubiquitin-conjugating enzyme UBE2D and the E3 ligase UHRF1. We resolve two CPL states: one is consistent with a ubiquitin-charged UBE2D, where ubiquitin is held in an open, inactive conformation by binding the scaffold protein PADI6; the second lacks discernible ubiquitin density and shows structural changes compatible with ubiquitin becoming available for transfer. Our findings support a model in which CPLs function as large ubiquitin ligase assemblies during early embryonic development.

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.

Jul 12, 2017. Major update of PDB

Major update of PDB

  • wwPDB released updated PDB data conforming to the new PDBx/mmCIF dictionary.
  • This is a major update changing the version number from 4 to 5, and with Remediation, in which all the entries are updated.
  • In this update, many items about electron microscopy experimental information are reorganized (e.g. em_software).
  • Now, EM Navigator and Yorodumi are based on the updated data.

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.
