OR2M3 (Olfactory Receptor, Family 2, Subfamily M, Member 3): OR2M3 is a gene that is part of the large olfactory receptor family responsible for the sense of smell. These receptors detect volatile odor molecules and are highly diverse, allowing the perception of a wide range of scents. OR2M3 is expressed in the olfactory epithelium of the nose and plays a crucial role in odor detection and signal transmission to the brain. Research on OR2M3 and related receptors contributes to a deeper understanding of smell and holds potential applications in flavor science and sensory biology.
