Rabbit antibody to TAS2R38

FUNCTION: Receptor that may play a role in the perception of bitterness and is gustducin-linked. May play a role in sensing the chemical composition of the gastrointestinal content. The activity of this receptor may stimulate alpha gustducin, mediate PLC-beta-2 activation and lead to the gating of TRPM5.
SUBCELLULAR LOCATION: Membrane; Multi-pass membrane protein.
TISSUE SPECIFICITY: Expressed in subsets of taste receptor cells of the tongue and exclusively in gustducin-positive cells.
POLYMORPHISM: Variations in TAS2R38 are associated with the ability to taste phenylthiocarbamide (PTC tasting); also called thiourea tasting. The ability to taste the substance PTC and a number of related substances is genetically controlled. Genetic studies have demonstrated complex inheritance for this trait. For some people (and some chimpanzees also), the chemical PTC tastes very bitter. For others, it is tasteless. Actually, substantial variation in taste sensitivity exists in human. Five haplotypes arising from three coding SNPs in the TAS2R38 gene are associated with distinct phenotypes of PTC taste sensitivity.
MISCELLANEOUS: Most taste cells may be activated by a limited number of bitter compounds; individual taste cells can discriminate among bitter stimuli.

IHC, WB. A dilution of 1 : 2000 is recommended. The optimal dilution should be determined by the end user. Not yet tested in other applications.

A synthetic peptide from human TAS2R38 conjugated to blue carrier protein was used as the antigen.
