Title: Lipids modulate the open probability of RyR1 under cryo-EM conditions.
Authors: Chenyao Li / Rouslan G Efremov /
Abstract: Ryanodine receptors (RyRs) are intracellular tetrameric ion channels responsible for Ca release from the sarcoplasmic and endoplasmic reticulum. Ryanodine receptor 1 (RyR1) isoform, critical for ...Ryanodine receptors (RyRs) are intracellular tetrameric ion channels responsible for Ca release from the sarcoplasmic and endoplasmic reticulum. Ryanodine receptor 1 (RyR1) isoform, critical for muscle contraction, has been studied most extensively. While cryoelectron microscopy (cryo-EM) has been instrumental in revealing near-atomic details of RyR gating mechanisms, the open probability of RyR1 under cryo-EM conditions is notably lower than that observed in electrophysiological studies. Here, we present a cryo-EM study examining the open probability of RyR1 solubilized in CHAPS with varying lipid concentrations. We found that increasing lipid concentration from 0.001% to 0.05% raised the RyR1 open probability from 16% to 84%, whereas RyR1 reconstituted into lipid nanodiscs remained closed. We modeled 72 lipid molecules in the map reconstructed at the highest lipid concentration. These findings demonstrate the important role of lipids in modulating the open fraction of solubilized RyR1 channels under cryo-EM conditions and suggest optimal lipid mimetics for structural studies of RyR1 gating.

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.

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.
