Polyclonal Rabbit Affinity Purified B IP IF
The mu-opioid receptor (MOR) belongs to the superfamily of G-protein-coupled receptors. MOR mediates the analgesic and rewarding effects of morphine and other opiates as well as the actions of several endogenous opioid peptides (1). Upon binding to its ligands, this Gi-coupled receptor inactivates adenylyl cyclase and activates a variety of G-beta-gamma-dependent pathways including the MAPK and the PI3K/Akt cascades. Trafficking of these receptors to and from the plasma membrane and their desensitization play a significant role in morphine tolerance. As with other GPCRs, these processes are modulated by phosphorylation at diverse sites within intracellular domain. Among other sites, agonist-specific phosphorylation of serine 375 in mouse (serine 377 in human) MOR is essential for its internalization.
