Olfactory receptor 2M4 is aprotein that in humans is encoded by theOR2M4gene.[3][4][5]
Olfactory receptors interact withodorant molecules in thenose, to initiate aneuronal response that triggers the perception of asmell. The olfactory receptorproteins are members of a large family of G-protein-coupled receptors (GPCR) arising from single coding-exongenes. Olfactory receptors share a 7-transmembrane domain structure with many neurotransmitter andhormone receptors and are responsible for the recognition and G protein-mediated transduction ofodorant 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.[5]
