Identify the organ that contains the highlighted epithelium. Gardella, T. J. Inferior. Another unresolved region in all existing structures of GPCR-arrestin complexes is located upstream of the key phosphorylation sites. (ed.) This supports close similarities between rhodopsin- and secretin-like GPCR interactions with arrestins, while suggesting that the NTS1R-arr2 structures, where arrestin is positioned in a nearly perpendicular orientation, either represent a distinct type of arrestin engagement or reflect specific experimental conditions, as discussed in ref.
