Agonist-induced Threonine363 phosphorylation of the κ-Opioid Receptor.
pT363-KOP (phospho-κ-Opioid Receptor Antibody)
Threonine363 is a major phosphorylation site of the kappa-opioid receptor (KOP). The pT363-KOP antibody detects phosphorylation in response to high-efficacy agonists. T363 phosphorylation is a key regulator of KOP desensitization,...

Validation of the κ-Opioid Receptor in transfected HEK293 cells.
KOP (non-phospho) κ-Opioid Receptor Antibody
The non-phospho-kappa-opioid receptor antibody is directed against the distal end of the carboxyl-terminal tail of mouse, rat and human KOP. It can be used to detect total KOP receptors in Western blots independent of phosphorylation.

KOP

Dynorphins are the endogenous ligands of the κ-opioid receptor (kappa-opioid receptor, KOP). U50,488H is a selective, high-efficacy κ-agonist. It has been proposed that G protein-biased kappa agonists such as nalfurafine or salvinorin B can reduce pain and itch, but exhibit fewer side effects such as sedation or dysphoria. KOP desensitization, trafficking and signaling are regulated by phosphorylation of carboxyl-terminal serine356/threonine357 (pS356/pT357-KOP) and threonine363 (pT363-KOP). Agonist-induced KOP phosphorylation can be mediated by multiple kinases including GRK2, GRK3, GRK5 and GRK6. S356 and T357 are also substrates for PKC-mediated phosphorylation. The designation of phosphorylation sites refers to the human KOP. This phosphorylation motif is also present in mice and rats.
