Advances in the Molecular Mechanism of Kappa Opioid Receptors Signaling and the Important Sampling Methods to Probe the Activation Landscape of GPCRs.

The kappa opioid receptor (KOR) is one of class A G-protein-coupled receptors (GPCRs), playing important roles in pain sensation. The unique analgesic activity of KOR requires KOR activation that recruits downstream effectors. It is noted that KOR pr…
