Title: TRPV1 antagonism occurs through diverse structural mechanisms.
Authors: Kyle E Lopez / Audrey S Paduda / Matthew J Derrick / Wade D Van Horn /
Abstract: Transient receptor potential vanilloid 1 (TRPV1) ion channel mediates thermosensation and pain and is a target for non-addictive analgesics; however, clinical candidates have failed due to ...Transient receptor potential vanilloid 1 (TRPV1) ion channel mediates thermosensation and pain and is a target for non-addictive analgesics; however, clinical candidates have failed due to thermoregulatory side effects. Limited structural data for human TRPV1 (hTRPV1) bound to clinically relevant antagonists has constrained mechanistic insight. Using chemoinformatics-informed cryo-EM and BRET assays, we define the structural basis of antagonism across diverse chemotypes, including failed clinical compounds. A structure of hTRPV1 bound to 6-iodo-dihydrocapsaicin shows how a single substitution converts an agonist into an antagonist. Additional structures with Asivatrep, Mavatrep, and JNJ-17203212 reveal vanilloid pocket plasticity and divergent interaction networks, including lipid co-binding. Despite this diversity, antagonists converge on a conserved inhibited state, showing high potency is maintained across flexible binding modes. These findings redefine our understanding of hTRPV1 antagonism and illustrate how chemically diverse ligands stabilize an inhibited state in polymodal ion channels, laying groundwork for next-generation analgesics with improved safety.

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.
