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 found in the olfactory epithelium, where they bind specific odor molecules and trigger signal pathways that result in the perception of smell. While the exact ligands and functions of OR13F1 are not yet fully understood, it plays a role in our sense of smell and may also be involved in pheromone detection.
