For a prototypical GPCR, the human vasopressin receptor type 2 (V2R), βarr1 can form a stable complex associated via only the phosphorylated carboxyl terminus of the receptor. Such a partially engaged complex is functionally competent with respect to supporting receptor internalization and ERK MAPK activation.
