Summaries for SSTR2 Gene

Entrez Gene Summary for 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. [provided by RefSeq, Jul 2008]

GeneCards Summary for SSTR2 Gene

SSTR2 (Somatostatin Receptor 2) is a Protein Coding gene. Diseases associated with SSTR2 include type c thymoma and pancreatic endocrine carcinoma. Among its related pathways are Signaling by GPCR and SIDS Susceptibility Pathways. GO annotations related to this gene include G-protein coupled receptor activity and neuropeptide binding. An important paralog of this gene is GALR2.

UniProtKB/Swiss-Prot for SSTR2 Gene

  • Receptor for somatostatin-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. Inhibits calcium entry by suppressing voltage-dependent calcium channels. Acts as the functionally dominant somatostatin receptor in pancreatic alpha- and beta-cells where it mediates the inhibitory effect of somatostatin-14 on hormone secretion. Inhibits cell growth through enhancement of MAPK1 and MAPK2 phosphorylation and subsequent up-regulation of CDKN1B. Stimulates neuronal migration and axon outgrowth and may participate in neuron development and maturation during brain development. Mediates negative regulation of insulin receptor signaling through PTPN6. Inactivates SSTR3 receptor function following heterodimerization.

Tocris Summary for SSTR2 Gene

  • Somatostatin (somatotropin release inhibiting factor, SRIF) is an endogenous cyclic polypeptide with two biologically active forms. It is an abundant neuropeptide and has a wide range of physiological effects on neurotransmission, secretion and cell proliferation.

    Quaternary structure:
    • Homodimer and heterodimer with SSTR3 and SSTR5. Heterodimerization with SSTR3 inactivates SSTR3 receptor function. Heterodimerization with SSTR5 is enhanced by agonist stimulation of SSTR2 and increases SSTR2 cell growth inhibition activity. Following agonist stimulation, homodimers dissociate into monomers which is required for receptor internalization. Interacts with beta-arrestin; this interaction is necessary for receptor internalization and is destabilized by heterodimerization with SSTR5 which results in increased recycling of SSTR2 to the cell surface. Interacts (via C-terminus) with SHANK1 (via PDZ domain).

Post-translational modifications for SSTR2 Gene

  • Phosphorylated on serine and threonine residues in response to agonist stimulation, leading to receptor desensitization and rapid internalization. Phosphorylated to a greater extent on serine than threonine residues. Threonine phosphorylation is required for arrestin binding and receptor endocytosis but is not necessary for desensitization (By similarity).

P30874-SSR2_HUMAN
Tissue specificity: Expressed in both pancreatic alpha- and beta-cells (at protein level). Expressed at higher levels in the pancreas than other somatostatin receptors. Also expressed in the cerebrum and kidney and, in lesser amounts, in the jejunum, colon and liver. In the developing nervous system, expressed in the cortex where it is located in the preplate at early stages and is enriched in the outer part of the germinal zone at later stages. In the cerebellum, expressed in the deep part of the external granular layer at gestational week 19. This pattern persists until birth but disappears at adulthood.
