OR6A2

Olfactory receptor 6A2 is a is_associated_with::protein that in humans is encoded by the OR6A2 is_associated_with::gene.

Function
is_associated_with::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 is_associated_with::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 is_associated_with::genome. The nomenclature assigned to the olfactory receptor genes and proteins for this organism is independent of other organisms.

Clinical significance
Variation in the OR6A2 gene has been identified as a likely cause of some people's strong dislike of is_associated_with::cilantro (also known as coriander).
