OR2AG1 - olfactory receptor family 2 subfamily AG member 1 Gene

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. This Olfactory Receptor gene is a segregating pseudogene, where some individuals have an allele that encodes a functional Olfactory Receptor, while other individuals have an allele encoding a protein that is predicted to be non-functional.
