OR8J2

Summary

OR8J2 (olfactory receptor family 8 subfamily J member 2 (gene/pseudogene), HGNC:15311) is a protein-coding gene on chromosome 11q12.1, encoding Olfactory receptor 8J2 (Q8NGG1). Odorant receptor.

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. This olfactory receptor gene is a segregating pseudogene, where some individuals have an allele that encodes a functional olfactory receptor, while other individuals have an allele encoding a protein that is predicted to be non-functional.
