The T1R1 receptor is a crucial component of the human taste system, specifically involved in the detection of umami, the savory taste of amino acids like glutamate. It functions by forming a heterodimer with the T1R3 receptor, enabling the perception of umami flavors in foods.

Glutamate is the most abundant excitatory neurotransmitter in the human central nervous system, playing a crucial role in synaptic plasticity, learning, and memory. It is also involved in neurotoxicity and is a key player in various neurological disorders when present in excessive amounts.

Heterodimer

The T1R3 receptor is a part of the taste receptor family responsible for detecting sweet and umami flavors, playing a crucial role in taste perception. It functions as a G-protein-coupled receptor, often forming heterodimers with T1R1 or T1R2 to mediate taste signaling pathways in humans and other animals.
