OR4K1

OR4K1 is a gene that encodes a protein in the olfactory receptor family. The olfactory receptors 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.

Function

The OR4K1 gene is part of the olfactory receptor family, a class of proteins that are responsible for detecting odors and sending signals to the brain. These proteins are located in the cell membranes of olfactory receptor neurons in the nose and are activated by odorant molecules.

Structure

The OR4K1 gene is located on chromosome 11 in humans. It is a single-exon gene, meaning it is made up of one continuous sequence of DNA. The protein it encodes is a member of the G-protein-coupled receptor (GPCR) family, which are integral membrane proteins that possess seven transmembrane domains.

Clinical Significance

While the specific role of OR4K1 in human health and disease is not yet fully understood, olfactory receptors in general are known to play a crucial role in the sense of smell. Disruptions in the function of these receptors can lead to anosmia, a condition characterized by a loss of the sense of smell.

Research

Research into the OR4K1 gene and its associated protein is ongoing. Understanding the function and structure of olfactory receptors like OR4K1 may provide insights into the mechanisms of smell and could potentially lead to the development of new therapeutic strategies for conditions like anosmia.
