相关性Peptide Histidine Methionine (PHM) is a 27 amino acid vasodilator peptide which shares 50% amino acid homology with vasoactive intestinal peptide (VIP) and which is encoded as part of the pro VIP molecule. Accordingly, all pro VIP derived neuropeptides are frequently colocalized, but appear to exert different physiological effects. The VIP/PHM prohormone is produced by neurons in the central and peripheral nervous systems, often together with acetylcholine. PHM belongs to the glucagon secretin family of peptide hormones and like VIP is a vasodilator and stimulator of intestinal fluid secretion.
