protein-coupled receptor (GPCR) ligands act as "biased agonists" that preferentially activate specific signaling Although GPCRs are primarily found at the plasma membrane, GPCRs can traffic to and signal from many Here, we determine that differential subcellular signaling contributes to the biased signaling generated Endosomal signaling is critical for biased activation of G proteins, β-arrestins, and extracellular-signal-regulated Our work demonstrates that differential subcellular signaling is critical to the overall biased response

ACKR3 has been described as an atypical "biased" receptor because it does not appear to signal through G proteins and, instead, signals solely through the β-arrestin pathway. In support of this conclusion, we have shown that ACKR3 is unable to signal through any of the known atypical chemokine receptor 3 (ACKR3), which signals atypically. This work will help to better understand the unique signaling roles of ACKR3."
