OR2W3
protein-coding gene in the species Homo sapiens
Olfactory receptor 2W3 is a protein that in humans is encoded by the OR2W3 gene.
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.

The public source identifies “OR2W3” as protein-coding gene in the species Homo sapiens. This brief keeps that definition visible, then builds a research path around OR2W3, protein-coding and gene.
Why this record matters
A short description can identify a subject without explaining its stakes. For “OR2W3”, the useful work is to connect “protein-coding gene in the species Homo sapiens” to the records capable of establishing context and consequence.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Jul 19, 2025. The linked authority identifier is Q18055544. None of the 0 selected statements returned an explicit reference.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
- Current terminology
- Classification context
