OR2W1

OR2W1 is a gene that provides instructions for making a protein that is part of the olfactory receptor family. The olfactory receptor family is a group of proteins that play a role in odor detection. The OR2W1 protein is specifically involved in the detection of certain odors.

Function

The OR2W1 gene belongs to the olfactory receptor gene family, which is the largest gene family in the genome. The 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.

Clinical significance

Variations in the OR2W1 gene have been associated with a person's sensitivity to certain smells. For example, some people may find the smell of a certain food to be pleasant, while others may find the same smell to be unpleasant. This difference in perception can be due to variations in the OR2W1 gene.
