Receptor ukusa tip 2 član 38 je protein koji je kod ljudi kodiran TAS2R38 genom. TAS2R38 je receptor gorkog ukusa. Različiti genotipi ovog receptora utiču na sposobnost prepoznavanja ukusa 6-n-propiltiouracila (PROP)[1] i feniltiokarbamida (PTC).[2][3] Though it has often been proposed that varying taste receptor genotypes could influence tasting ability, TAS2R38 is one of the only taste receptors shown to have this function.[4]

Prenos signala

uredi

Kao i kod svih TAS2R proteina, TAS2R38 koristi G-protein gustducin kao svoj primarni metod prenosa signala. Jedinice α i βγ su esencijalne za prenos signala ukusa.[5]
