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