SSTR4 (somatostatin receptor 4)

Gene

• Entrez ID: 6754
• Gene name: Somatostatin receptor 4
• Gene symbol: SSTR4
• Synonyms (NCBI Gene): SS-4-R, SS4-R, SS4R, SST4
• Chromosome: 20
• Chromosome location: 20p11.21
• Summary: 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. S

Protein

• UniProt ID: P31391
• Protein name: Somatostatin receptor type 4 (SS-4-R) (SS4-R) (SS4R) (SST4)
• Protein function: Receptor for somatostatin-14. The activity of this receptor is mediated by G proteins which inhibits adenylyl cyclase. It is functionally coupled not only to inhibition of adenylate cyclase, but also to activation of both arachidonate release an
