It exists in two active forms produced by alternative cleavage of a single preproprotein (14 aa and 28 aa forms). Somatosatin inhibits the release of growth hormone; thyroid-stimulating hormone and a range of gastrointestinal hormones: Cholecystokinin (CCK); Enteroglucagon; Gastrin; Gastric inhibitory polypeptide (GIP); Motilin; Secretin; Vasoactive intestinal peptide (VIP).
