GENERAL INFORMATIONi

General description of the gene and the encoded protein(s) using information from HGNC and Ensembl, as well as predictions made by the Human Protein Atlas project.

Human gene namei

Official gene symbol, which is typically a short form of the gene name, according to HGNC.

OR5AC2
Human gene
descriptioni

Full gene name according to HGNC.

Olfactory receptor family 5 subfamily AC member 2
Predicted locationi

All transcripts of all genes have been analyzed regarding the location(s) of corresponding protein based on prediction methods for signal peptides and transmembrane regions.

  • Genes with at least one transcript predicted to encode a secreted protein, according to prediction methods or to UniProt location data, have been further annotated and classified with the aim to determine if the corresponding protein(s) are secreted or actually retained in intracellular locations or membrane-attached.
  • Remaining genes, with no transcript predicted to encode a secreted protein, will be assigned the prediction-based location(s).

The annotated location overrules the predicted location, so that a gene encoding a predicted secreted protein that has been annotated as intracellular will have intracellular as the final location.

HUMAN PROTEIN ATLAS INFORMATIONi

Intra-species specificity categories. Summary of RNA Tissue specificity per organsim based on its full tissue repertoire.

Brain expression
cluster (RNA)i

The RNA data was used to cluster genes according to their expression across tissues. Clusters contain genes that have similar expression patterns, and each cluster has been manually annotated to describe common features in terms of function and specificity.

Not detected - no cluster assigned
Tissue specificityi

The RNA specificity category is based on mRNA expression levels in the consensus dataset which is calculated from the RNA expression levels in samples from HPA and GTEX. The categories include: tissue enriched, group enriched, tissue enhanced, low tissue specificity and not detected.

The tissue data for RNA expression obtained through Cap Analysis of Gene Expression (CAGE) generated by the FANTOM project are reported as Scaled Tags Per Million. Color-coding is based on tissue groups, each consisting of tissues with functional features in common. To access sample data, click on tissue name or bar.

The CAGE method is described in detail here.

Not detected
Human brain
Regional specificityi

The regional specificity category is based on mRNA expression levels in the analysed brain samples, grouped into 13 main brain regions and calculated for the three different species. All brain expression profiles are based on data from HPA. The specificity categories include: regionally enriched, group enriched, regionally enhanced, low regional specificity and not detected. The classification rules are the same used for the tissue specificity category.

Not detected
Domain specificity Not detected
Tau specificity scorei

Tau specificity score is a numerical indicator of the specificity of the gene expression across cells or tissues. The value ranges from 0 and 1, where 0 indicates identical expression across all cells/tissue types, while 1 indicates expression in a single cell/tissue type.

Not detected
Regional distributioni

The regional distribution category is based on mRNA expression detected above cut off or not in the analysed brain samples, grouped into 13 main brain regions and calculated for the three different species. Brain expression for all species is based on data from HPA. The distribution categories include: detected in all, detected in many, detected in some, detected in single and not detected. The classification rules are the same used for the tissue distribution category.

BRAIN RNA EXPRESSIONi

The data is based on "bulk" RNAseq of micro-punched brain areas and brain nuclei. The size of the punches was adjusted to the size of the brain region to obtain detailed protein expression information on distinct cell populations. Multiple samples were collected from the same donors allowing a mild normalization and correction for individual variation. Data is expressed as normalized tags per million (nTPM). Protein expression data is organized on the 13 main brain structures representing the maximum value found in any of the brain areas that make up that structure. A detailed overview of the expression in any of the brain areas is summarized in bar plots for each brain structure.

SINGLE NUCLEI BRAINi

The data is based on Siletti K et al. (2023) public data. Color-coding is based on cell type groups (as defined in the single cell type data representing the whole body), in this case separated into the main cell categories of neuron, glial cells, endothelial cells, fibroblasts and muscle cell (vascular smooth muscle cells and pericytes).
