OR13F1 (Olfactory Receptor, Family 13, Subfamily F, Member 1): OR13F1 is a protein belonging to the olfactory receptor gene family — a group of G protein-coupled receptors responsible for detecting odors. These receptors are located in the olfactory epithelium, where they bind to specific odor molecules and initiate signalling pathways that lead to the perception of smell. Although the exact ligands and functions of OR13F1 are not fully defined yet, it contributes to our sense of smell and may also be involved in detecting pheromones.
