Human bitter taste receptors hTAS2R8 and hTAS2R39 with differential functions to recognize bitter peptides

Biosci Biotechnol Biochem. 2011;75(6):1188-90. doi: 10.1271/bbb.100893. Epub 2011 Jun 13.

Abstract

The strong bitter peptide, Phe-Phe-Pro-Arg, activated cultured cells expressing either of the known human bitter taste receptors, hTAS2R8 and hTAS2R39. The partial structure of Pro-Arg activated hTAS2R39, but did not activate hTAS2R8. These receptors may not indiscriminately recognize bitter peptides, but have a differential function in their recognition.
