1 Here we report on the identification of Arg-336 and Asn-333 of CCK-AR, which interact with the Asp-8 carboxylate and the C-terminal amide of CCK-9, respectively. Amides cholecystokinin Homo sapiens
2 Arg-336-Asp-8 and Asn-333-amide interactions were pharmacologically assessed by mutational exchange of Arg-336 and Asn-333 in the receptor or reciprocal elimination of the partner chemical functions in CCK. Amides cholecystokinin Homo sapiens
