Biology:OR4F5

Short description: Protein-coding gene in the species Homo sapiens

Generic protein structure example

Olfactory receptor family 4 subfamily F member 5 is a protein that in humans is encoded by the OR4F5 gene.

Function

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

Trivia

OR4F5 is the first protein coding gene on human chromosome 1.
