Figure 3 Binding selectivity of the vasoactive intestinal peptide/pituitary adenylate cyclase activating polypeptide receptors. Pituitary adenylate cyclase activating polypeptide receptor 1 (PAC1) selectively binds pituitary adenylate cyclase activating polypeptide (PACAP) with 1000-fold greater affinity than vasoactive intestinal peptide (VIP), whereas vasoactive intestinal peptide receptor (VPAC)1 and VPAC2 bind VIP and PACAP with equal affinity.
