The highlighted structures are folds (cellular extensions) of the cell _____ membrane. Which epithelium is responsible for protection, secretion, and absorption? To generate initial rough models of PTHLA-PTH1R-arr2 complexes, all published GPCR-arrestin complexes, including rhodopsin-arr1 (PDBID: 5W0P)20, 1-ARarr2 (PDBID: 6TKO)24, M2R-arr2 (PDBID: 6U1N)23 and NTS1R-arr2 (PDBID: 6PWC and 6UP7)21,22, were used as templates to define arrestin conformation and its orientation with respect to the PTH1R receptor. To monitor these angles along the MD trajectory, principal components (PCs) of arr2 coordinates (C only) were calculated on the fly and sorted in descent according to their eigenvalues; the longitudinal axis, vertical axis, and transverse axis of arr2 are defined as PC1, PC2, and PC3, respectively.

This is consistent with a reduction of the distance between BRET-donor and -acceptor and suggests that thedistal C-tail of PTH1R beyond residue P524 protrudes into the cytosol and does not interact with arrestin. While highlighting the dynamics of the PTH1R-arr2 complex, MD simulations revealed its overall stability and robust key interactions within the interface, including both at the 7TM domain and phosphorylation clusters of the C-terminal tail of PTH1R.
