GPCR Structures: mu and kappa opioid structures



So, two more GPCR structures in last weeks Nature magazine. This time two paralogous opioid receptors, the mu (human UniProt:P35372) and kappa (human UniProt:P41145) subtypes, one from mouse, the other from human, and both complexed to synthetic antagonists. These continue to add to our ability to understand and predict pharmacology of known and future drugs, but also will be great examples for engagement with the public over science - everyone has heard of opiates, and heroin and morphine, even my kids have!

Here's an alignment for the 13 sequence distinct structures; I don't think it's completely right in several places, but it is a challenging family to align completely and certainly it's not unambiguous, but it's a start.

  1. 3uon - human muscarinic M2 receptor 
  2. 4daj - rat muscarinic M3 receptor 
  3. 3rze - human histamine H1 receptor
  4. 2rh1 - human beta-2 adrenergic receptor 
  5. 2vt4 - turkey beta-1 adrenergic receptor 
  6. 3pbl - human dopamine D3 receptor
  7. 2ydv - human adenosine A2a receptor 
  8. 3v2w - human sphingosine-1-phosphate receptor 
  9. 4djh - human kappa opioid receptor 
  10. 4dkl - mouse mu opioid receptor 
  11. 3odu - human CCR4 receptor 
  12. 2i35 - bovine rhodopsin 
  13. 2z73 - squid rhodopsin
