Abstract excerpt
Arrestins selectively bind to phosphorylated activated forms of their cognate G protein-coupled receptors. Arrestin binding prevents further G protein activation and often redirects signaling to other pathways. The comparison of the high-resolution crystal structures of arrestin2, visual arrestin, and rhodopsin as well as earlier mutagenesis and peptide inhibition data collectively suggest that the elements on...
