OR4A16
OR4A16 encodes an olfactory receptor, a seven-transmembrane G-protein-coupled receptor expressed in olfactory sensory neurons that binds specific odorant molecules and triggers the neural signaling cascade underlying smell perception. A genome-wide association study of odor identification found that the locus tagged by rs669453, which colocalizes with OR4A16 (along with nearby OR4C16 and OR8U8), is strongly associated with a person's ability to identify a pineapple odor.
