Somatostatin receptor type 2 is a protein that in humans is encoded by the SSTR2 gene.

Somatostatin acts at many sites to inhibit the release of many hormones and other secretory proteins. The biologic effects of somatostatin are probably mediated by a family of G protein-coupled receptors that are expressed in a tissue-specific manner. SSTR2 is a member of the superfamily of receptors having seven transmembrane segments and is expressed in highest levels in cerebrum and kidney.

Interactions

Somatostatin receptor 2 has been shown to interact with SHANK1.
