產(chǎn)品介紹 The sense of taste is essential for the survival of organisms. For example, the ability to identify sweet-tasting foods enables animals to seek out food with high nutritive value, whereas the ability to identify bitter substances enables them to avoid the ingestion of potentially harmful substances. A family of integral membrane proteins are involved in taste perception and include T1R, which is involved in sweet taste perception and T2R, which is involved in bitter taste perception. Both types of taste receptors couple to various G proteins to initiate signal transduction cascades. Specifically, T2R38 is expressed in subsets of taste receptor cells of the tongue and exclusively in gustducin-positive cells. Variations in T2R38 are associated with the ability to taste the bitter chemical phenylthiocarbamide (PTC), also called thiourea tasting.

Function : TAS2R38 is gustducin-linked and may play a role in the perception of bitterness and in sensing the chemical composition of the gastrointestinal content. The activity of this receptor may stimulate alpha gustducin, mediate PLC-beta-2 activation and lead to the gating of TRPM5.

Subcellular Location : Membrane; Multi-pass membrane protein.

Tissue Specificity : Expressed in subsets of taste receptor cells of the tongue and exclusively in gustducin-positive cells.

Similarity : Belongs to the G-protein coupled receptor T2R family.

Database links : UniProtKB/Swiss-Prot: P59533.3

TAS2R38是一種苦味味覺感受器，該感受器可以嘗出苯硫脲和丙硫氧嘧啶或者相關(guān)物質(zhì)的苦味。這一點(diǎn)和大多數(shù)苦味感受器有所不同，即該感受器是對某類物質(zhì)敏感，而大多數(shù)感受器則不會表現(xiàn)出強(qiáng)烈的選擇性，能對多種物質(zhì)做出響應(yīng)。該感受器所能嘗出的相應(yīng)物質(zhì)大量存在于西蘭花、卷心菜以及其它十字花科植物中，例如：葡萄糖異硫氰酸鹽及其相關(guān)產(chǎn)物異硫氰酸酯。目前全球人類中，約有75%該感受器相關(guān)基因正常，即，可以嘗出苦味。而剩下的25%則無法嘗出這類的苦味，或者敏感度較低。
