Title: Structural insights into the ligand and G protein recognition by P2YR.

Abstract: P2Y purinergic receptors are GPCRs that recognize extracellular nucleotides to mediate diverse physiological processes. Among 12-like subfamily members, P2YR has well-documented roles in ...P2Y purinergic receptors are GPCRs that recognize extracellular nucleotides to mediate diverse physiological processes. Among 12-like subfamily members, P2YR has well-documented roles in neuroprotection and cholesterol metabolism. Notably, P2YR displays robust activity toward the G pathway in addition to its canonical G coupling, yet the structural basis for its ligand recognition and G protein selectivity has remained unclear. Here, we present the cryo-EM structure of the P2YR-G complex bound to ADP at a resolution of 2.83 Å. The structure reveals the distinctive ligand recognition mechanism of P2YR, in which an N-terminal arginine caps the orthosteric binding pocket. Furthermore, we also elucidated the structure of P2YR, which shows the lowest G activation ability among the 12-like P2Y receptors, in complex with UDP and G at a resolution of 2.93 Å. Structural comparison with the 12-like P2Y receptors implicates ICL2-mediated contacts with the Gα hydrophobic cavity as a key structural determinant of G selectivity. Together, these findings provide mechanistic insights into nucleotide signaling and a structural foundation for advancing structure-based approaches to targeting the 12-like P2Y 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.
