Abstract excerpt
Protein kinase C (PKC) activation plays an important role in morphine-induced μ-opioid receptor (OPRM1) desensitization and tolerance development. It was recently shown that receptor phosphorylation by G protein-coupled receptor kinase regulates agonist-dependent selective signaling and that inefficient phosphorylation of OPRM1 leads to PKCε activation and subsequent responses. Here, we demonstrate that such...
