Olfactory receptor 2K2 is aprotein that in humans is encoded by theOR2K2gene.[5][6][7]
Olfactory receptors interact with odorant molecules in thenose, to initiate a neuronal response that triggers the perception of asmell. The olfactory receptor proteins are members of a large family of G-protein-coupled receptors (GPCR) arising from single coding-exon genes. Olfactory receptors share a 7-transmembrane domain structure with many neurotransmitter and hormone receptors and are responsible for the recognition and G protein-mediated transduction of odorant signals. The olfactory receptor gene family is the largest in the genome. The nomenclature assigned to the olfactory receptor genes and proteins for this organism is independent of other organisms.[7]
