CAN channels are involved in cellular responses such as neuronal bursting activity and cardiac rhythm. Here we report the electron cryo-microscopy structure of the most widespread CAN channel, human TRPM4, bound to the agonist Ca and the modulator decavanadate. Four cytosolic C-terminal domains form an umbrella-like structure with a coiled-coil domain for the 'pole' and four helical 'ribs' spanning the N-terminal TRPM homology regions (MHRs), thus holding four subunits in a crown-like architecture. We observed two decavanadate-binding sites, one in the C-terminal domain and another in the intersubunit MHR interface. A glutamine in the selectivity filter may be an important determinant of monovalent selectivity. Our structure provides new insights into the function and pharmacology of both the CAN and the TRPM families.

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.

Jul 12, 2017. Major update of PDB

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.
