Overview

« Hide More detailed introduction

Somatostatin (somatotropin release inhibiting factor) is an abundant neuropeptide, which acts on five subtypes of somatostatin receptor (sst1–sst5; nomenclature approved by the NC-IUPHAR Subcommittee on Somatostatin Receptors, [6]). Activation of these receptors produces a wide range of physiological effects throughout the body including inhibiting the secretion of many hormones. The relationship of the cloned receptors to endogenously expressed receptors is not yet well established in some cases. Endogenous ligands for these receptors are somatostatin-14 (SRIF-14 (SST, P61278)) and somatostatin-28 (SRIF-28 (SST, P61278)). Cortistatin (CST-14) has also been suggested to be an endogenous ligand for somatostatin receptors [3].
