Oligonucleotides were purchased from Microsynth (Balgach, CH) and Biomers (Ulm, DE). The path of the receptor C-terminus is largely defined by the formation of an extended -sheet between -strand I of the arrestin (residues V8 to A12) and the -strand in the PTH1R C-terminus (V500S504) that overlaps with the distal phosphorylation cluster (S501T506). 115, 455465 (2002).
