Comparison of (A) a minimimum energy conformer of diphosphorylated CB1419-438 fragment bound to arrestin and (B) the seven phosphorylated Rh330-348 fragment bound to visual arrestin. This later structure was downloaded from the protein data bank (www.rcsb.org.1NZS.pdb) and oriented to highlight the similarity of the C-terminal end with CB1419-438. The phosphorylated residues are highlighted by CPK representations.
