'''Olfactory receptor 4M2''' is a [[protein]] that in humans is encoded by the ''OR4M2'' [[gene]].<ref name="entrez">{{cite web | title = Entrez Gene: OR4M2 olfactory receptor, family 4, subfamily M, member 2| url = https://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=390538}}</ref>

Olfactory receptors interact with odorant molecules in the nose, to initiate a neuronal response that triggers the perception of a smell. 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.<ref name="entrez" />
