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 genomic coordinates used for the transcript record were based on alignments.

The RefSeq Genes track shows known human protein-coding and
non-protein-coding genes taken from the NCBI RNA reference sequences
collection (RefSeq). The data underlying this track are updated daily.
Display Conventions and Configuration
This track follows the display conventions for
gene prediction tracks.
The color shading indicates the level of review the RefSeq record has
undergone: predicted (light), provisional (medium), reviewed (dark).
The item labels and display colors of features within this track can be
configured through the controls at the top of the track description page.
This page is accessed via the small button to the left of the track's
graphical display or through the link on the track's control menu.
Label: By default, items are labeled by gene name. Click the
appropriate Label option to display the accession name instead of the gene
name, show both the gene and accession names, or turn off the label
Codon coloring: This track contains an optional codon coloring
feature that allows users to quickly validate and compare gene predictions.
To display codon colors, select the genomic codons option from the
Color track by codons pull-down menu. For more information about this
feature, go to the
Coloring Gene Predictions and Annotations by Codon page.
Hide non-coding genes: By default, both the protein-coding and
non-protein-coding genes are displayed. If you wish to see only the coding
genes, click this box.
RefSeq RNAs were aligned against the human genome using blat; those
with an alignment of less than 15% were discarded. When a single RNA
aligned in multiple places, the alignment having the highest base identity
was identified. Only alignments having a base identity level within 0.1% of
the best and at least 96% base identity with the genomic sequence were kept.
This track was produced at UCSC from RNA sequence data generated by scientists
worldwide and curated by the NCBI
