GENERAL INFORMATIONⁱ General description of the gene and encoded protein(s) using information from HGNC and Ensembl, as well as predictions made as well as predictions made by the Human Protein Atlas project.
Human gene nameⁱ Gene name according to HGNC.	SLC1A3
Mouse gene name	Slc1a3
Human gene description	Solute carrier family 1 member 3
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 INFORMATION
Tissue specificityⁱ The RNA specificity category is based on mRNA expression levels in the analyzed samples based on a combination of data from HPA, GTEX and FANTOM5. The categories include: tissue enriched, group enriched, tissue enhanced, low tissue specificity and not detected. The Tissue classification is based on 37 human tissue types, where brain is represented by the highest expression value among the human brain regions (including spinal cord and corpus callosum that is excluded from the regional classification based on 10 main brain regions). The combination of tissue and regional classification can be found here Read more	Tissue enriched (brain)
	Human brain	Pig brain	Mouse brain
Regional specificityⁱ The regional specificity category is based on mRNA expression levels in the analyzed brain samples, grouped into 10 main brain regions and calculated for the three different species. The human brain expression profile is based on a combination of data from GTEX and FANTOM5. 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. Read more	Low region specificity	Low region specificity	Low region specificity
Regional distributionⁱ The regional distribution category is based on mRNA expression detected above cut off or not in the analyzed brain samples, grouped into 10 main brain regions and calculated for the three different species. The human brain expression is based on a combination of data from GTEX and FANTOM5. 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. Read more	Detected in all	Detected in all	Detected in all
Cellular locationⁱ Manually selected location of the protein positivity, observed by immunofluorescence staining in mouse brain. Read more	Endfeet in astrocytes. Ventricle wall and circumventricular organs of ependymal cells.
Protein profileⁱ 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. Read more	SLC1A3 (also known as GLAST or EAAT1) is a glutamate transporter, whose RNA transcripts are highly enriched in the human CNS, with widespread expression across numerous brain regions. In the mouse, immunohistochemical staining of astrocytes (endfeet) is observed in many regions throughout the brain, strongly in olfactory, thalamus, hypothalamus and cerebellum.

	Consensus Human brain datasetⁱ Consensus normalized expression (NX) levels were created for the 10 brain regions by combining the data from two transcriptomics datasets (GTEx and FANTOM5). Color coding is based on brain region and the bar shows the highest expression among the subregions included. To access sample data, click on region name or bar. Read more about how the datasets were combined into consensus normalized expression levels in Assays & Annotation. GTEx Human brain RNA-Seq datasetⁱ GTEx dataset RNA-seq tissue data generated by the Genotype-Tissue Expression (GTEx) project is reported as mean pTPM (protein-coding transcripts per million), 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. The GTEx RNA-seq assay is described in detail in Assays & Annotation. FANTOM5 Human brain CAGE datasetⁱ 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. The CAGE method is described in detail in Assays & Annotation.
	HPA Pig brain RNA-Seq datasetⁱ HPA Pig dataset HPA RNA-seq tissue data is reported as mean NX (normalized expression) for the 10 brain regions.
