Abstract: Our skin safeguards the body homeostasis for health and also provides psychological consolation in social life. Natural essential oils are widely used for skin maintenance, while the molecular target ...Our skin safeguards the body homeostasis for health and also provides psychological consolation in social life. Natural essential oils are widely used for skin maintenance, while the molecular target and mechanism of action remain largely unknown. Here, we report that citronellal, a plant-derived acyclic monoterpene commonly used for personal care, stimulates skin renewal by promoting keratinocyte proliferation through the activation of TRPV3. We further present cryo-EM structures of human TRPV3 in complex with acyclic monoterpenes, including citronellal, citral, linalool and isodihydrolavandulal, determined at resolutions of 3.1-3.6 Å. Our structural and functional analysis unmasks consistent yet subtly different binding modes within the TRPV3 vanilloid site. Our results elucidate that essential oil ligands activate TRPV3 channels by competitively displacing endogenous lipids from the vanilloid site. Together, these findings identify TRPV3 as the molecular target of natural acyclic monoterpenes for skin renewal, and delineate the structural basis of action, thus being instrumental for moving forward skin healthcare.

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.

Yorodumi

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.
