VIPR1/VPAC1 Proteins and Enzymes

The Vasoactive Intestinal Polypeptide Receptor 1 (VPAC1) is a member of a family of three G-protein coupled receptors which mediate VIP (vasoactive intestinal peptide; a small neuropeptide) and PACAP (pituitary adenlyate cyclase activating peptide) function in a variety of tissues. Together, the VPAC1 and VPAC2 receptors compose a subtype of the VIP receptor. Expression of the VIP and PACAP receptors has been linked to the presence of human tumors. Vasoactive intestinal peptide is involved in ...
