Human Gene SSTR4 (ENST00000255008.5)
  Description: Homo sapiens somatostatin receptor 4 (SSTR4), mRNA. (from RefSeq NM_001052)
RefSeq Summary (NM_001052): 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. 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. [provided by RefSeq, Jul 2008].

-  Comments and Description Text from UniProtKB
DESCRIPTION: RecName: Full=Somatostatin receptor type 4; Short=SS-4-R; Short=SS4-R; Short=SS4R;
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 and mitogen-activated protein (MAP) kinase cascade. Mediates antiproliferative action of somatostatin in tumor cells.
SUBCELLULAR LOCATION: Cell membrane; Multi-pass membrane protein.
TISSUE SPECIFICITY: Specifically expressed in fetal and adult brain, lung tissue, stomach, and in lesser quantities in the kidney, pituitary and adrenals.
SIMILARITY: Belongs to the G-protein coupled receptor 1 family.

ModBase Predicted Comparative 3D Structure on P31391
The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.

-  Orthologous Genes in Other Species
  Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
