Taste receptor type 2 member 50 is a protein that in humans is encoded by the TAS2R50 gene.^[5]^[6]^[7]^[8]

Function

TAS2R50 belongs to the large TAS2R receptor family. TAS2Rs are expressed on the surface of taste receptor cells and mediate the perception of bitterness through a G protein-coupled second messenger pathway.^[6] See also TAS2R10.^[8]
