Polyclonal Rabbit Serum E B
Control of appetite involves a number of gastrointestinal hormones that belong to the ghrelin-motilin ligand family that either stimulate food intake and gastric emptying or inhibit these responses. These hormones have been the focus of intense research in hopes of developing drug therapy for gastrointestinal and eating disorders. GPR39 is a G protein-coupled receptor (GPCR). It is sequentially distantly related to the growth hormone secretagogue receptor (ghrelin) and neurotensin receptors. Its endogenous ligand was unknown until 2005, when an amidated 23aa peptide, obestatin, was found to bind to it specifically. Interestingly, these two peptides appear to have opposite effects. While ghrelin stimulates appetite by acting on its receptor in the arcuate nucleus, obestatin suppresses appetite.
Catalog #G8600-43K
GPR39 mouse 456aa; human: 453aa -51kD; Chromosome: 2q21-q22. Expressed in many tissues and brain regions. GPR39 is alternatively spliced. Full length GPR39-1a (456aa in mouse with 7 TM domains) and truncated form (GPR39-1b; 315aa with 5 TM domains). Quantitative RT-PCR analysis demonstrated that GPR39-1a is expressed selectively throughout the gastrointestinal tract, including the liver and pancreas as well as in the kidney and adipose tissue, whereas the truncated GPR39-1b form has a more broad expression pattern, including the central nervous system but with highest expression in the stomach and small intestine.
ApplicationsSuitable for use in ELISA and Western Blot. Other applications not tested.
Recommended DilutionELISA: 1:100,000
Western Blot: 1-10ug/ml
