Olfactory Receptor 10A3 (OR10A3)

OR10A3 belong to the different family from them, so the pattern of seven points is different. In addition, it could be concluded that the tendency of spatial configuration of TM-helices were preserved in seven mid-points.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.
