Tas2r118 Gene Summary [Rat]
Predicted to enable bitter taste receptor activity. Predicted to be involved in detection of chemical stimulus involved in sensory perception of bitter taste. Predicted to be located in endoplasmic reticulum; external side of plasma membrane; and trans-Golgi network. Predicted to be active in membrane. Human ortholog(s) of this gene implicated in alcohol dependence. Orthologous to human TAS2R16 (taste 2 receptor member 16). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Tas2r118 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
- G-protein coupled receptor
- taste receptor
- Taste receptor protein (TAS2R)
