TAS2R20

TAS2R20 is a gene that encodes a protein known as a bitter taste receptor. This receptor is part of the TAS2R (Taste 2 Receptor) family, a group of proteins that are responsible for the detection of bitter compounds in the human mouth. The TAS2R20 receptor is specifically tuned to detect certain bitter compounds, contributing to the overall perception of bitterness in foods and beverages.

Function[edit | edit source]

The TAS2R20 gene is expressed in the taste buds on the tongue, where it encodes a protein that forms part of the bitter taste receptor. When a bitter compound is present in the mouth, it binds to the TAS2R20 receptor, triggering a signal that is sent to the brain. This signal is interpreted as a bitter taste.

The TAS2R20 receptor is particularly sensitive to certain bitter compounds, including some that are found in foods such as broccoli, Brussels sprouts, and coffee. This sensitivity can vary between individuals, depending on variations in the TAS2R20 gene. Some people may have a version of the gene that makes them more sensitive to these bitter compounds, while others may have a version that makes them less sensitive.

Clinical significance[edit | edit source]

Variations in the TAS2R20 gene can have a significant impact on an individual's dietary preferences and habits. People who are more sensitive to bitter tastes may be less likely to consume bitter foods and beverages, which can have implications for their overall diet and health.

In addition, the TAS2R20 gene has been implicated in certain health conditions. For example, some research has suggested that variations in this gene may be associated with an increased risk of alcoholism. However, more research is needed to fully understand the potential health implications of variations in the TAS2R20 gene.
