Description
Helospectin I is a peptide originally found in Heloderma lizards. Helospectin I is a neuropeptide of the vasoactive intestinal peptide (VIP) family that exhibits vasodilatory and antihypertensive activities, decreasing blood pressure in vivo. Additionally, helospectin I increases plasma glucagon in animal models.
