Peptide ELISA

Detection limit 1:32000
Application Notes
WB: Preliminary experiments gave an approx. 27 kDa band in human colon and testis lysates and in cell lines NIH 3T3, A431 and Kelly after 0.1 ug/ml antibody staining. Please note that currently we cannot find an explanation in the literature for the band we observe given the calculated size of 40.4 kDa band according to NP_001095856.1. The 27 kDa band was successfully blocked by incubation with the immunizing peptide.
Please Note: Optimal dilutions of this antibody should be experimentally determined.

Background: GNAT3

Function: Guanine nucleotide-binding protein (G protein) alpha subunit playing a prominent role in bitter and sweet taste transduction as well as in umami (monosodium glutamate, monopotassium glutamate, and inosine monophosphate) taste transduction. Transduction by this alpha subunit involves coupling of specific cell-surface receptors with a cGMP-phosphodiesterase; Activation of phosphodiesterase lowers intracellular levels of cAMP and cGMP which may open a cyclic nucleotide-suppressible cation channel leading to influx of calcium, ultimately leading to release of neurotransmitter. Indeed, denatonuim and strychnine induce transient reduction in cAMP and cGMP in taste tissue, whereas this decrease is inhibited by GNAT3 antibody. Gustducin heterotrimer transduces response to bitter and sweet compounds via regulation of phosphodiesterase for alpha subunit, as well as via activation of phospholipase C for beta and gamma subunits, with ultimate increase inositol trisphosphate and increase of intracellular Calcium. GNAT3 can functionally couple to taste receptors to transmit intracellular signal: receptor heterodimer TAS1R2/TAS1R3 senses sweetness and TAS1R1/TAS1R3 transduces umami taste, whereas the T2R family GPCRs act as bitter sensors. Functions also as lumenal sugar sensors in the gut to control the expression of the Na+-glucose transporter SGLT1 in response to dietaty sugar, as well as the secretion of Glucagon-like peptide-1, GLP-1 and glucose-dependent insulinotropic polypeptide, GIP. Thus, may modulate the gut capacity to absorb sugars, with implications in malabsorption syndromes and diet-related disorders including diabetes and obesity.; Subcellular location: cytoplasm; Tissue specificity: Expressed in taste buds (sensory organs of clustered epithelial cells) of the circumvallate and fungiform papillae of the tongue as well as in palatal taste buds at protein level. Expressed in enteroendocrine cells of the gut, such as in subsets of enteroendocrine cells in the midjejunum and brush cells. Detected also in spermatozoa.
