OR3A1
Description
The OR3A1 (olfactory receptor family 3 subfamily A member 1) is a protein-coding gene located on chromosome 17.
OR3A1 is a human protein encoded by the OR3A1 gene. It is an olfactory receptor responsible for detecting odors. Olfactory receptors interact with odorant molecules in the nose, initiating a signal that results in the perception of a smell. OR3A1 is activated by helional and heliotropylacetone, but not by piperonal, safrole, or vanillin. Other agonists include lilial, cyclamen aldehyde, and foliaver (3-(4-methoxyphenyl)-2-methylpropanal). Like other olfactory receptors, OR3A1 is a G-protein-coupled receptor (GPCR) with a 7-transmembrane domain structure. The olfactory receptor gene family is the largest in the genome, and the nomenclature used for these genes and proteins is unique to humans.
Olfactory receptor. OR3A1, also known as OR17-40 or OR17-15, is a protein that binds to odorant molecules in the nose, triggering a signal that results in the perception of smell. It's a member of the G-protein-coupled receptor (GPCR) family and shares a common structure with many other receptors involved in neurotransmission and hormone signaling.
OR3A1 is also known as OLFRA03, OR17-40, OR17-82, OR40.
