Significant advancements in the cellular biology of G protein-coupled receptors (GPCRs) about a novel biosensor shed light on the endosomal proteome associated with the δ-opioid receptor (DOR). Upon agonist activation, the DOR-APEX2 complex is internalized and trafficked to the lysosome. the endosomal proteome associated with the DOR receptor. This fluorescence serves as a readout for the activity of APEX2 and, by extension, the trafficking of

G protein-coupled receptors (GPCRs) are a vast family of membrane-bound proteins crucial for transmitting the initial GPCR-G protein association step, ensuring precise downstream signalling activation. Traditionally, it was believed that GPCRs selectively activate only their cognate G protein subtypes, typically necessary for G protein activation. prepare the GPCR in a manner that optimizes subsequent cognate G protein activation.

GPCR activation typically occurs through the binding of agonists which stabilize receptor conformations conformation without agonist engagement referred to as receptor constitutive or basal activity. The initial demonstration of spontaneous or "constitutive" receptor activity was reported for the β2- Subsequently, opioid receptors were shown to constitutively activate Gi proteins in a membrane preparation of receptor constitutive activity.
