Title: Rapid small-scale nanobody-assisted purification of ryanodine receptors for cryo-EM.

Abstract: Ryanodine receptors (RyRs) are large Ca release channels residing in the endoplasmic or sarcoplasmic reticulum membrane. Three isoforms of RyRs have been identified in mammals, the disfunction of ...Ryanodine receptors (RyRs) are large Ca release channels residing in the endoplasmic or sarcoplasmic reticulum membrane. Three isoforms of RyRs have been identified in mammals, the disfunction of which has been associated with a series of life-threatening diseases. The need for large amounts of native tissue or eukaryotic cell cultures limits advances in structural studies of RyRs. Here, we report a method that utilizes nanobodies to purify RyRs from only 5 mg of total protein. The purification process, from isolated membranes to cryo-EM grade protein, is achieved within 4 h on the bench, yielding protein usable for cryo-EM analysis. This is demonstrated by solving the structures of rabbit RyR1, solubilized in detergent, reconstituted into lipid nanodiscs or liposomes, and bovine RyR2 reconstituted in nanodisc, and mouse RyR2 in detergent. The reported method facilitates structural studies of RyRs directed toward drug development and is useful in cases where the amount of starting material is limited.

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.
