Somatostatin Receptor

Somatostatin receptor is a family of G protein-coupled seven transmembrane receptors. Somatostatin acts at many sites to inhibit the release of many hormones and other secretory proteins. The biological effects of somatostatin are probably mediated by a family of G protein-coupled receptors that are expressed in a tissue-specific manner. Include SSTR1, SSTR2, SSTR3, SSTR4, SSTR5. SSTR1 is expressed in highest levels in jejunum and stomach. SSTR2 is a member of the superfamily of receptors having seven transmembrane segments and is expressed in highest levels in cerebrum and kidney. SSTR3 is functionally coupled to adenylyl cyclase. SSTR4 is a member of the superfamily of receptors having seven transmembrane segments and is expressed in highest levels in fetal and adult brain and lung. SSTR5 is a member of the superfamily of receptors having seven transmembrane segments.
