Kenya and EIB to partner on RE sources for green hydrogen 22. 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. We thank the staff at the USC Center for Advanced Research Computing for providing computational resources and Felix Nitzsche for the synthesis of BrEtY in Leipzig. Understanding the molecular basis of arrestin-mediated regulation of GPCRs is critical for deciphering signaling mechanisms and designing functional selectivity.
