Title: Structural mechanisms of potent lysophosphatidic acid receptor 1 activation by nonlipid basic agonists.
Authors: Hiroaki Akasaka / Fumiya K Sano / Wataru Shihoya / Osamu Nureki /
Abstract: Lysophosphatidic acid receptor 1 (LPA) is one of the G protein-coupled receptors activated by the lipid mediator, lysophosphatidic acid (LPA). LPA is associated with a variety of diseases, and LPA ...Lysophosphatidic acid receptor 1 (LPA) is one of the G protein-coupled receptors activated by the lipid mediator, lysophosphatidic acid (LPA). LPA is associated with a variety of diseases, and LPA agonists have potential therapeutic value for treating obesity and depression. Although potent nonlipid LPA agonists have recently been identified, the mechanisms of nonlipid molecule-mediated LPA activation remain unclear. Here, we report a cryo-electron microscopy structure of the human LPA-G complex bound to a nonlipid basic agonist, CpY, which has 30-fold higher agonistic activity as compared with LPA. Structural comparisons of LPA with other lipid GPCRs revealed that the negative charge in the characteristic binding pocket of LPA allows the selective recognition of CpY, which lacks a polar head. In addition, our structure show that the ethyl group of CpY directly pushes W271 to fix the active conformation. Endogenous LPA lacks these chemical features, which thus represent the crucial elements of nonlipid agonists that potently activate LPA. This study provides detailed mechanistic insights into the ligand recognition and activation of LPA by nonlipid agonists, expanding the scope for drug development targeting the LPA receptors.

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.
