Abstract: The peptide hormone angiotensin II regulates blood pressure mainly through the type 1 angiotensin II receptor AT R and its downstream signaling proteins G and β-arrestin. AT R blockers, clinically ...The peptide hormone angiotensin II regulates blood pressure mainly through the type 1 angiotensin II receptor AT R and its downstream signaling proteins G and β-arrestin. AT R blockers, clinically used as antihypertensive drugs, inhibit both signaling pathways, whereas AT R β-arrestin-biased agonists have shown great potential for the treatment of acute heart failure. Here, we present a cryo-electron microscopy (cryo-EM) structure of the human AT R in complex with a balanced agonist, Sar -AngII, and G protein at 2.9 Å resolution. This structure, together with extensive functional assays and computational modeling, reveals the molecular mechanisms for AT R signaling modulation and suggests that a major hydrogen bond network (MHN) inside the receptor serves as a key regulator of AT R signal transduction from the ligand-binding pocket to both G and β-arrestin pathways. Specifically, we found that the MHN mutations N111 A and N294 A induce biased signaling to G and β-arrestin, respectively. These insights should facilitate AT R structure-based drug discovery for the treatment of cardiovascular diseases.

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.

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.
