Overview of Gene Research
Otop1, or Otopetrin 1, is a proton-selective ion channel with multiple essential functions. It is involved in sour taste sensing in taste receptor cells, the formation of otoconia in the inner ear, and potentially in alkaline sensation in vertebrates [1,3,5]. It participates in the transduction of taste signals, a crucial pathway for organisms to sense and respond to various taste stimuli [4].
In gene knockout studies, Otop1-/-mouse strains have provided significant insights. In taste-related research, taste responses to NH4Cl measured from isolated Type III taste receptor cells (TRCs) or gustatory nerves were strongly attenuated or eliminated in Otop1-/-mice, revealing its role in mediating a major component of the taste of NH4Cl [2]. Also, knockout of Otop1 eliminated acid responses from sour-sensing TRCs, indicating its essentiality for sour sensing in the taste system [3].
In conclusion, Otop1 is a key ion channel involved in taste-related sensing processes such as sour and ammonium taste detection. The use of Otop1 knockout mouse models has been instrumental in uncovering its role in taste transduction, which may have implications for understanding taste-related disorders and potentially developing novel taste-modifying therapies.
