Title: Structural basis of cooling agent and lipid sensing by the cold-activated TRPM8 channel.
Authors: Ying Yin / Son C Le / Allen L Hsu / Mario J Borgnia / Huanghe Yang / Seok-Yong Lee /
Abstract: Transient receptor potential melastatin member 8 (TRPM8) is a calcium ion (Ca)-permeable cation channel that serves as the primary cold and menthol sensor in humans. Activation of TRPM8 by cooling ...Transient receptor potential melastatin member 8 (TRPM8) is a calcium ion (Ca)-permeable cation channel that serves as the primary cold and menthol sensor in humans. Activation of TRPM8 by cooling compounds relies on allosteric actions of agonist and membrane lipid phosphatidylinositol 4,5-bisphosphate (PIP), but lack of structural information has thus far precluded a mechanistic understanding of ligand and lipid sensing by TRPM8. Using cryo-electron microscopy, we determined the structures of TRPM8 in complex with the synthetic cooling compound icilin, PIP, and Ca, as well as in complex with the menthol analog WS-12 and PIP Our structures reveal the binding sites for cooling agonists and PIP in TRPM8. Notably, PIP binds to TRPM8 in two different modes, which illustrate the mechanism of allosteric coupling between PIP and agonists. This study provides a platform for understanding the molecular mechanism of TRPM8 activation by cooling agents.

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.
