OR3A1
An Error has occurred retrieving Wikidata item for infobox Olfactory receptor 3A1 is a protein that in humans is encoded by the OR3A1 gene.[1][2][3] 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.[3]
Ligands
OR3A1 is activated by helional and the closely related molecule heliotropylacetone.[4] Other compounds including piperonal, safrole, and vanillin completely failed to activate OR3A1. Agonists:
- helional[4]
- heliotropylacetone[4]
- lilial[5]
- cyclamen aldehyde[5]
- foliaver (3-(4-methoxyphenyl)-2-methylpropanal)[5]
