Anti-SSTR2 Somatostatin Receptor 2

0.5mg/ml if reconstituted with 0.2ml sterile DI water. 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. Stable transfection of human pancreatic cells, which do not endogenously express SSTR2, inhibits cell proliferation, tumorigenicity, and metastasis. These effects occur as a consequence of an autocrine SSTR2-dependent loop, whereby SSTR2 induces expression of its own ligand, somatostatin. mRNA was variably expressed in all neuroblastoma tumors with a relevant reduction in the more advanced stage. Protein function: 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. [The UniProt Consortium]
