Abstract: The ternary complex, composed of eIF2, GTP and initiator methionyl-tRNA, delivers the first amino acid to the ribosome to initiate protein synthesis. Eukaryotic initiation factor 2B (eIF2B) catalyzes ...The ternary complex, composed of eIF2, GTP and initiator methionyl-tRNA, delivers the first amino acid to the ribosome to initiate protein synthesis. Eukaryotic initiation factor 2B (eIF2B) catalyzes GDP to GTP exchange on eIF2, thereby setting the ternary complex level. Stress-induced phosphorylation converts eIF2 from the substrate of eIF2B into an inhibitor (eIF2-P). This conversion reduces ternary complex levels and induces the integrated stress response (ISR). Here we chart an allosteric axis running through eIF2B, revealing the importance of an α-helix in its β-subunit, the 'latch-helix', that hooks onto the α-subunit to induce eIF2B activity. eIF2-P binding promotes latch-helix unhooking, opening eIF2B, which inhibits its activity. Convergently evolved viral proteins stabilize this latch-helix-binding active state of eIF2B. Using these insights, we generated ISR-activating compounds that stabilize eIF2B in its inhibited, unlatched state. Our study thus highlights how long-range eIF2B allostery can be pharmacologically manipulated to sustain or attenuate the ISR.

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.
