OR5H14 (Olfactory Receptor Family 5 Subfamily H Member 14): OR5H14 is part of the olfactory receptor (OR) gene family, which is responsible for detecting and binding odour molecules. These receptors play a key role in the sense of smell. The specific ligands and precise function of OR5H14 in olfaction are not yet fully understood, but it contributes to the complexity and diversity of smell perception.
