Description
Function: Putative taste receptor. TAS1R1/TAS1R3 responds to the umami taste stimulus (the taste of monosodium glutamate) and also to most of the 20 standard L-amino acids, but not to their D-enantiomers or other compounds. Sequence differences within and between species can significantly influence the selectivity and specificity of taste responses.Subunit: Forms heterodimers with TAS1R3.Subcellular location: Cell membrane, Multi-pass membrane protein.Tissue specificity: Expressed strongly only in fungiform papillae. Also known as: Taste receptor, type 1, member 2a, tas1r2.1, TAS1R2a.
Immunogen
A synthetic peptide from internal region of zebrafish taste receptor, type 1, member 2a (TAS1R2a, tas1r2.1) conjugated to an immunogenic carrier protein was used as the antigen.
