Growth hormone-inhibiting hormone (GHIH), also referred to as somatostatin or by a number of other names, is a peptide hormone that regulates the endocrine system and influences neurotransmission and cell proliferation through interactions with G protein-coupled somatostatin receptors and the inhibition of the release of numerous secondary hormones. Somatostatin prevents the release of glucagon and insulin.
A single preproprotein is split into two active forms of somatostatin, one with 14 amino acids (as indicated in the infobox to the right) and the other with 28 amino acids.
