PACAP-27, the N-terminal fragment of PACAP-38, is a neuropeptide originally isolated from bovine hypothalamus, but is also found in humans and rats. It shows considerable homology with Vasoactive Intestinal Polypeptide (VIP), but stimulates adenylate cyclase much more potently than VIP. PACAP27 and PACAP38 stimulate cAMP accumulation and increase [Ca2+]i through the type I PACAP receptors.
