Summary

Story summary

USC researchers used cryo-electron microscopy to capture structural snapshots of the mu-opioid receptor (MOR) during activation and inhibition.
The structures show how morphine and Narcan interact with the mu-opioid receptor.
The study provides insights into nucleotide release mechanisms.
The findings could guide the development of safer painkillers and improved overdose treatments to address the opioid crisis.
