Somatostatin

Somatostatin, polypeptide that inhibits the activity of certain pancreatic and gastrointestinal hormones. Somatostatin exists in two forms: one composed of 14 amino acids and a second composed of 28 amino acids. The name somatostatin, essentially meaning stagnation of a body, was coined whe Pasireotide is a synthetic polypeptide analogue of somatostatin that resembles the native hormone in its ability to suppress levels and activity of growth hormone, insulin, glucagon and many other gastrointestinal peptides. Because its half-life is longer than somatostatin, pasireotide can be used clinically to treat neuroendocrine pituitary tumors that secrete excessive amounts of growth. Somatostatin. Somatostatin (SS) is a 14- and 28-amino acid peptide discovered in 1973, which is synthesized in neurons and in delta cells of the pancreas. From: Handbook of Neuroendocrinology, 2012. Download as PDF Somatostatin is a hormone that many different tissues produce, but it is found primarily in the nervous and digestive systems. The primary function of somatostatin is to prevent the production of other hormones and also stop the unnatural rapid reproduction of cells — such as those that may occur in tumors

somatostatin: (SRIF, SS) [ so″mah-to-stat´in ] a cyclic tetradecapeptide hormone and neurotransmitter that inhibits the release of peptide hormones in many tissues. It is released by the hypothalamus to inhibit the release of growth hormone (GH, somatotropin) and thyroid stimulating hormone (TSH) from the anterior pituitary; it is also.

Somatostatin is a cyclic peptide well known for its strong regulatory effects throughout the body. Also known by the name of growth hormone inhibiting hormone, it is produced in many locations, which include the gastrointestinal (GI) tract, pancreas, hypothalamus, and central nervous system (CNS) Using an anglerfish somatostatin probe, Shen et al. (1982) cloned SST from a human pancreatic somatostatinoma cDNA library. The deduced 116-amino acid precursor protein has a calculated molecular mass of 12.7 kD. It has an N-terminal signal sequence, and the C-terminal 28 or 14 amino acids are proteolytically released as mature somatostatin-28 or somatostatin-14 peptides, respectively Receptor for somatostatin-14 and -28. This receptor is coupled via pertussis toxin sensitive G proteins to inhibition of adenylyl cyclase. In addition it stimulates phosphotyrosine phosphatase and PLC via pertussis toxin insensitive as well as sensitive G proteins. Inhibits calcium entry by suppressing voltage-dependent calcium channels. Acts as the functionally dominant somatostatin receptor.
