Abstract: Transient receptor potential vanilloid subfamily member 3 (TRPV3) channel plays a crucial role in skin physiology and pathophysiology. Mutations in TRPV3 are associated with various skin diseases, ...Transient receptor potential vanilloid subfamily member 3 (TRPV3) channel plays a crucial role in skin physiology and pathophysiology. Mutations in TRPV3 are associated with various skin diseases, including Olmsted syndrome, atopic dermatitis, and rosacea. Here we present the cryo-electron microscopy structures of full-length mouse TRPV3 in the closed apo and agonist-bound open states. The agonist binds three allosteric sites distal to the pore. Channel opening is accompanied by conformational changes in both the outer pore and the intracellular gate. The gate is formed by the pore-lining S6 helices that undergo local α-to-π helical transitions, elongate, rotate, and splay apart in the open state. In the closed state, the shorter S6 segments are entirely α-helical, expose their nonpolar surfaces to the pore, and hydrophobically seal the ion permeation pathway. These findings further illuminate TRP channel activation and can aid in the design of drugs for the treatment of inflammatory skin conditions, itch, and pain.

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.
