ChemiSCREEN Membrane Preparation Recombinant Human sst5 Somatostatin Receptor

Descrição detalhada : Full-length human SSTR5 cDNA encoding sst5, Somatostatin (sst) is a multifunctional peptide with two biologically active forms, sst-14 and sst-28, which are synthesized in neurons throughout the brain as well as in peripheral tissues such as the pancreas and the gut (Gillies, 1997). SST exerts a diverse array of effects that include inhibition of endocrine secretion, modulation of neurotransmission, and regulation of cell proliferation by stimulating a family of five G-protein-coupled receptors. Somatostatin receptor sst5 is an inhibitory G protein-coupled receptor that exerts a strong cytostatic effect on various cell types. In mice, sst5 mediates inhibition by somatostatin of pancreatic insulin secretion and contributes to the regulation of glucose homeostasis and insulin sensitivity (Strowski et al. 2003). In addition, deficiency of sst5 leads to subtype-selective sexually dimorphic changes in the expression of both brain and pancreatic somatostatins (Ramirez et al. 2004). Millipore's sst5 membrane preparations are crude membrane preparations made from our proprietary stable recombinant cell lines to ensure high-level of GPCR surface expression; thus, they are ideal HTS tools for screening of agonists and antagonists of sst5. The membrane preparations exhibit a Kd of 1.2 nM for [125I]-Somatostatin 14. With 0.5 nM [125I]-Somatostatin 14, 5 mug/well sst5 Membrane Prep typically yields greater than 10-fold signal-to-background ratio.
