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). In this study, the DOR receptor was genetically fused to APEX2, creating a DOR-APEX2 construct. the vicinity, allowing the capture of a snapshot of the endosomal proteome associated with the DOR receptor
