Abstract: Apolipoprotein B100 (apoB100) is a structural component of low-density lipoprotein (LDL) and a ligand for the LDL receptor (LDLR). Mutations in apoB100 or in LDLR cause familial ...Apolipoprotein B100 (apoB100) is a structural component of low-density lipoprotein (LDL) and a ligand for the LDL receptor (LDLR). Mutations in apoB100 or in LDLR cause familial hypercholesterolaemia, an autosomal dominant disease that is characterized by a marked increase in LDL cholesterol (LDL-C) and a higher risk of cardiovascular disease. The structure of apoB100 on LDL and its interaction with LDLR are poorly understood. Here we present the cryo-electron microscopy structures of apoB100 on LDL bound to the LDLR and a nanobody complex, which can form a C-symmetric, higher-order complex. Using local refinement, we determined high-resolution structures of the interfaces between apoB100 and LDLR. One binding interface is formed between several small-ligand-binding modules of LDLR and a series of basic patches that are scattered along a β-belt formed by apoB100, encircling LDL. The other binding interface is formed between the β-propeller domain of LDLR and the N-terminal domain of apoB100. Our results reveal how both interfaces are involved in LDL dimer formation, and how LDLR cycles between LDL- and self-bound conformations. In addition, known mutations in either apoB100 or LDLR, associated with high levels of LDL-C, are located at the LDL-LDLR interface.

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.
