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.
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.
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 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.
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.
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.
A summary of the overall protein localization across the analyzed brain tissue. The summary is based on manual annotation.
Mouse brain profiles includes a more extensive summary of the protein location while summaries with only human protein profile are more limited and are based on imported data/images from the Tissue Atlas stainings that has undergone an additional brain-centric curation step.
The Opioid receptor mu 1 is an inhibitory G-protein coupled receptor that can exhibit a presynaptic or postsynaptic pattern, with its RNA transcripts showing weak to moderate expression throughout the human brain. In the mouse, however, strong but spatially highly restricted immunoreactivity is seen in a few nuclei/axonal tracts throughout the brain, where dendritic network as well as occasional cells bodies are also depicted. The staining is restricted to parts of the habenulointerpeduncular pathway, septofimbrial nucleus, stria medullaris, some 'islets' of the caudate putamen, the nucleus accumbens, parts of the lateral septum, the lateral parabrachial nucleus, the periaqueductal gray and the caudal subdivision of the dorsal raphe. In addition, less intense, diffuse synaptic staining is noticed in the central medial and paraventricular thalamic nuclei.

COMPARISON BRAIN RNA EXPRESSION
GTEX AND FANTOM HUMAN BRAIN
GTEx Human brain RNA-Seq dataseti
GTEx dataset RNA-seq tissue data generated by the Genotype-Tissue Expression (GTEx) project is reported as mean nTPM, corresponding to mean values of the different individual samples for respective subregion. Highest expression among the subregions represents the brain region. To access sample data, click on region name or bar.
FANTOM5 dataset Tissue data for RNA expression obtained through Cap Analysis of Gene Expression (CAGE) generated by the FANTOM5 project are reported as Scaled Tags Per Million. To access sample data, click on region name or bar.
HPA Pig dataset HPA RNA-seq tissue data is reported as mean nTPM (normalized expression) for each of the brain regions analyzed in pig. The detailed pages (reached when clicking a bar or regional name) show nTPM values at the individual sample level. To access sample data, click on region name or bar.
The pig brain transcriptomics project is a collaborative project between human protein atlas and the Lars Bolund institute of regenerative Medicine (Dr. Yonglun Luo), BGI-Qingdao, China.
HPA Mouse dataset HPA RNA-seq tissue data is reported as mean nTPM (normalized expression) for each of the brain regions analyzed in mouse. The detailed pages (reached when clicking a bar or regional name) show nTPM values at the individual sample level. To access sample data, click on region name or bar.
The Human brain protein data is based on curated and manually selected Tissue Atlas data. The standard brain regions used in the Tissue Atlas are cerebral cortex, caudate nucleus, hippocampus and cerebellum, only selected cases include information on hypothalamus or retina. The score is based on knowledge-based annotation of the protein location in the main cell types. For genes where more than one antibody has been used, a collective score is set displaying the estimated true protein expression.
Non curated brain data available in the Tissue Atlas.
MOUSE BRAIN PROTEIN LOCATIONi
Mouse brain protein profiles are based in serial sections of the adult mouse brain analyzed by immunofluorescence. The staining intensity and regional distribution is manually summarized.

HPA Mouse staining intesityi
The score is based on the relative fluorescence, defined as intensity of the annotated region relative to the intensity of the region with highest intensity. The digitalized images are processed (axel-adjusted and tissue edges defined) and regions of interest (ROIs) are then marked. These ROIs are then used for image analysis and the relative fluorescence intensity is listed for each region. For more data and regional information click on the bar or the regional name.
