    HOMOLOGY
    interspecies ortholog to a bitter cluster on murine chromosome 6
    Homologene
    FAMILY
  • G protein coupled receptor superfamily
  • taste receptor family
  • CATEGORY receptor membrane G
    SUBCELLULAR LOCALIZATION     plasma membrane
    basic FUNCTION
  • taste receptor cells of the tongue and palate epithelia
  • 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 gastro intestinal content
  • may stimulate alpha gustducin, mediate PLC-beta-2 activation and lead to the gating of TRPM5
