OR4F29

Summary

OR4F29 (olfactory receptor family 4 subfamily F member 29, HGNC:31275) is a protein-coding gene on chromosome 1p36.33, encoding Olfactory receptor 4F3/4F16/4F29 (Q6IEY1). 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.
