[[http://www.uniprot.org/uniprot/OPRK_HUMAN OPRK_HUMAN]] G-protein coupled opioid receptor that functions as receptor for endogenous alpha-neoendorphins and dynorphins, but has low affinity for beta-endorphins. Also functions as receptor for various synthetic opioids and for the psychoactive diterpene salvinorin A. Ligand binding causes a conformation change that triggers signaling via guanine nucleotide-binding proteins (G proteins) and modulates the activity of down-stream effectors, such as adenylate cyclase. Signaling leads to the inhibition of adenylate cyclase activity. Inhibits neurotransmitter release by reducing calcium ion currents and increasing potassium ion conductance. Plays a role in the perception of pain. Plays a role in mediating reduced physical activity upon treatment with synthetic opioids. Plays a role in the regulation of salivation in response to synthetic opioids. May play a role in arousal and regulation of autonomic and neuroendocrine functions.<ref>PMID:12004055</ref> <ref>PMID:22437504</ref> <ref>PMID:7624359</ref> <ref>PMID:8060324</ref>

Opioid receptors mediate the actions of endogenous and exogenous opioids on many physiological processes, including the regulation of pain, respiratory drive, mood, and--in the case of kappa-opioid receptor (kappa-OR)--dysphoria and psychotomimesis. Here we report the crystal structure of the human kappa-OR in complex with the selective antagonist JDTic, arranged in parallel dimers, at 2.9 A resolution. The structure reveals important features of the ligand-binding pocket that contribute to the high affinity and subtype selectivity of JDTic for the human kappa-OR. Modelling of other important kappa-OR-selective ligands, including the morphinan-derived antagonists norbinaltorphimine and 5'-guanidinonaltrindole, and the diterpene agonist salvinorin A analogue RB-64, reveals both common and distinct features for binding these diverse chemotypes. Analysis of site-directed mutagenesis and ligand structure-activity relationships confirms the interactions observed in the crystal structure, thereby providing a molecular explanation for kappa-OR subtype selectivity, and essential insights for the design of compounds with new pharmacological properties targeting the human kappa-OR.
