Abstract: Inhibition of γ-secretase activity represents a potential therapeutic strategy for Alzheimer's disease (AD). MRK-560 is a selective inhibitor with higher potency for Presenilin 1 (PS1) than for PS2, ...Inhibition of γ-secretase activity represents a potential therapeutic strategy for Alzheimer's disease (AD). MRK-560 is a selective inhibitor with higher potency for Presenilin 1 (PS1) than for PS2, the two isoforms of the catalytic subunit of γ-secretase, although the underlying mechanism remains elusive. Here we report the cryo-electron microscopy (cryo-EM) structures of PS1 and PS2-containing γ-secretase complexes with and without MRK-560 at overall resolutions of 2.9-3.4 Å. MRK-560 occupies the substrate binding site of PS1, but is invisible in PS2. Structural comparison identifies Thr281 and Leu282 in PS1 to be the determinant for isoform-dependent sensitivity to MRK-560, which is confirmed by swapping experiment between PS1 and PS2. By revealing the mechanism for isoform-selective inhibition of presenilin, our work may facilitate future drug discovery targeting γ-secretase.

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.

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.
