After 48h, the media was aspirated and the cells were stimulated for 90min with 1mL activation buffer supplemented with 200nM PTH(1-34). Our crosslinking data show that this segment of PTH1R comes close to the positively charged region at the distal edge of the arrestin N-domain (N-edge), comprised of the 160-loop and the loop between -strands IV and V. This arrangement is compatible with the available GPCR-arrestin structures, since the proximal GPCR C-tail is pushed away from the central crest of arrestin by the presence of the 7TM domain, so that this negatively charged region is optimally positioned to interact with the N-edge.
