WebThe delta opioid receptor (DOP) belongs to the Class A, rhodopsin-like family of G protein-coupled receptors. Although this receptor has a high level of similarity with the other opioid receptors, it displays unique aspects and functions. Indeed, as opposed to most membrane receptors, DOP is poorly addressed to the plasma membrane. WebResults of radioligand binding and transfected receptor studies indicate that mu-receptor down-regulation and phosphorylation may be critical to the expression of morphine …
