The classical model of arrestin-mediated desensitization of cell-surface G protein-coupled receptors (GPCRs) is thought to be universal. However, this paradigm is incompatible with recent reports that the parathyroid hormone (PTH) receptor (PTHR), a crucial GPCR for bone and mineral ion metabolism, sustains GS activity and continues to generate cAMP for prolonged periods after ligand-wash-out; during these periods the receptor is observed mainly in endosomes, associated with the bound ligand, GS and β-arrestins. In this review, we discuss possible molecular mechanisms underlying sustained signaling by the PTHR, including modes of signal generation and attenuation within endosomes, as well as the biological relevance of such non-canonical signaling.
