Extra Details:: GPR39 (G-protein coupled receptor 39) is an orphan GPCR receptor from ghrelin/motilin receptor subfamily of G-protein coupled receptor 1 family, and it is constitutively active with Zn2+ as its physiological agonist. GPR39 is a multipass transmembrane protein found in cell membranes and is expressed in several tissues such as stomach, intestine and hypothalamus. Obestatin, a 23 amino acid peptide originating from ghrelin precursor, was originally shown to be the endogenous ligand of GPR39, a study that happened to be non-reproducible, and later on it was shown that obestatin does not bind, nor activate GPR39 but that Zn2+ could stimulate GPR39 signalling in vitro, thereby inferring that obestatin is not the natural ligand of GPR39. GPR39 receptor also displays a strong ligand-independent signaling activity through G-alpha12/13 as well as G-alphaq. This receptor mediates its action by association with G proteins that activate a phosphatidylinositol-calcium second messenger system. GPR39 has been shown to implicate in the regulation of insulin release/pancreatic function, body weight, gastrointestinal mobility, hormone secretion and cell death. Applications: Suitable for use in Immunocytochemistry/Immunofluorescence and Immunohistochemistry. Other applications not tested. Recommended Dilution: Immunohistochemistry (paraffin): 1:50, prior to immunostaining paraffin tissues, antigen retrieval with sodium citrate buffer (pH 6.0) is recommended. Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for 12 months after receipt. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
