Abstract: Overexpression of exportin 1 (XPO1/CRM1) in cancer cells mislocalizes numerous cancer-related nuclear export cargoes. Covalent selective inhibitors of nuclear export (SINEs), including the cancer ...Overexpression of exportin 1 (XPO1/CRM1) in cancer cells mislocalizes numerous cancer-related nuclear export cargoes. Covalent selective inhibitors of nuclear export (SINEs), including the cancer drug selinexor, restore proper nuclear localization by blocking XPO1-cargo interaction. These inhibitors also induce XPO1 degradation through the Cullin-RING E3 ligase (CRL) substrate receptor ASB8. Here we present cryo-electron microscopy structures revealing ASB8 binding to a cryptic XPO1 site that is exposed upon SINE conjugation. Unlike typical molecular glue degraders that directly bridge CRLs and substrates, SINEs bind XPO1 independently of ASB8, triggering an allosteric mechanism that enables high-affinity ASB8 recruitment, leading to XPO1 ubiquitination and degradation. ASB8-mediated degradation is also triggered by the endogenous itaconate derivative 4-octyl itaconate, suggesting that synthetic XPO1 inhibitors exploit a native cellular mechanism. This allosteric XPO1 degradation mechanism expands known modes of targeted protein degradation beyond molecular glue degraders and proteolysis-targeting chimeras of CRL4.

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.
