Human Gene SSTR2 (ENST00000357585.4) from GENCODE V44
  Description: Homo sapiens somatostatin receptor 2 (SSTR2), mRNA. (from RefSeq NM_001050)
RefSeq Summary (NM_001050): 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. [provided by RefSeq, Jul 2008].

-  Comments and Description Text from UniProtKB
DESCRIPTION: RecName: Full=Somatostatin receptor type 2; Short=SS-2-R; Short=SS2-R; Short=SS2R; AltName: Full=SRIF-1;
FUNCTION: Receptor for somatostatins-14 and -28. This receptor is coupled via pertussis toxin sensitive G proteins to inhibition of adenylyl cyclase. In addition it stimulates phosphotyrosine phosphatase and PLC via pertussis toxin insensitive as well as sensitive G proteins. In RIN-5F cells, this receptor inhibits calcium entry by suppressing voltage dependent calcium-channels.
SUBUNIT: The C-terminus interacts with SHANK1 PDZ domain.
INTERACTION: P32745:SSTR3; NbExp=3; IntAct=EBI-6266898, EBI-6266935;
SUBCELLULAR LOCATION: Cell membrane; Multi-pass membrane protein.
TISSUE SPECIFICITY: Cerebrum and kidney. In lesser amounts in jejunum, colon and liver.
SIMILARITY: Belongs to the G-protein coupled receptor 1 family.

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.
