- Endosomal parathyroid hormone receptor signaling
October 2022 "The canonical model for G protein-coupled receptors (GPCRs) activation assumes that stimulation In this model, GPCR signaling is turned-off by receptor phosphorylation via GPCR kinases (GRKs) and subsequent recruitment of β-arrestins, resulting in receptor internalization into endosomes. Internalized receptors can then recycle back to the cell surface or be trafficked to lysosomes for degradation This is the case for the parathyroid hormone (PTH) type 1 receptor (PTHR), which engages on sustained
