Amino acid sequence of the two receptor variants and three phosphopeptide variants. The receptor sequences are shown starting from residue F336 though C341 of β₂AR, followed by the V₂ receptor C tail residues. The phosphorylated residues in the receptor V2 tail and phosphopeptides are shown in bold and underlined. The positions of the sites of phosphorylation have the assigned numbering P1 to P8 denoted as a subscript for each residue.
