Location bias contributes to functionally selective responses of biased CXCR3 agonists

Abstract

Subcellular signaling is critical to generating cellular responses that modulate inflammatory pathways at the chemokine receptor CXCR3. Eiger et al. determine that agonist-biased CXCR3 signaling at endosomes differs from that at the plasma membrane, proposing location bias as an important phenomenon in signal transduction.
