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.
Gene namei
Official gene symbol, which is typically a short form of the gene name, according to HGNC.
Assigned HPA protein class(es) for the encoded protein(s).
Disease related genes Enzymes Human disease related genes Metabolic proteins Potential drug targets
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.
Intracellular
Number of transcriptsi
Number of protein-coding transcripts from the gene as defined by Ensembl.

HUMAN PROTEIN ATLAS INFORMATIONi
Summary of RNA expression and protein localization based on data generated within the Human Protein Atlas project.
Main locationi
Main subcellular location(s) and reliability score(s) for the encoded protein(s) in human cells. The main location(s) may be characterized by presence in all tested cell lines and/or ihigher staining intensity compared to the potential additional location(s). If available, links to overrepresentation analyses in Reactome, a free, open-source, curated and peer reviewed biological pathway database, are provided. An analysis is done for the corresponding gene set of the proteome localizing to the main and additional locations of the protein on this page, respectively.
Localized to the Peroxisomes (approved)
Additional locationi
Additonal subcellular location(s) for the encoded protein(s) in human cells. The additional location(s) may not be present i all cell lines and may have lower staining intensity compared to the main location(s). If available, links to overrepresentation analyses in Reactome, a free, open-source, curated and peer reviewed biological pathway database, are provided. An analysis is done for the corresponding gene set of the proteome localizing to the main and additional locations of the protein on this page, respectively.
In addition localized to the Nucleoli (approved)
Single-cell variationi
Single-cell variations in protein expression levels or distribution observed between cells within the same images of human cells stained by immunocytochemistry.
Single-cell variation in protein expression observed.
Reliability scorei
Overall gene reliability score for the subcellular location(s) of the encoded protein(s). The score indicates the level of reliability of the annotated protein localization based on agreement with available experimental gene/protein characterization data in the UniProtKB/Swiss-Prot database and presence of antibody validation assays for immunocytochemistry.

Additional locationi
Additonal subcellular location(s) for the encoded protein(s) in human cells. The additional location(s) may not be present i all cell lines and may have lower staining intensity compared to the main location(s).
Assay for determining the subcellular location of the encoded protein(s) in human cells by indirect immunofluorescence and confocal microscopy. The antibody-based staining is generally carried out in U2OS and two additional cell lines, selected based on RNA expression. Representative multi-color images showing the protein of interest in green are displayed below. The images also include markers for the nucleus (blue), microtubules (red) and ER (yellow). All images are clickable for an enlarged view. For cell structure reference, visit the cell dictionary.
Buttons for turning on and off the different channels in the multi-color images. The intensity toggle shows the pixel intensity range in 16 different colors for the selected channel. The object toggle shows the computational segmentation of the cells used for further analysis in the HPA project. For samples where cell cycle dependency for the protein is suggested according to a correlation assay the predicted cell cycle position of each cell is displayed when using the object toggle.

Cell line RNA Expression (nTPM)i
RNA expression level in the cell line based on normalised RNA sequencing data. Genes with a value above 1 NX are considered to be expressed.
Locationi
Observed subcellular location(s).
Single-cell variationi
Observed single-cell variation(s) in the staining pattern. Variation in protein expression levels can be observed as varaiations in the intensity of the immunofluorescent signal, while spatial variations can be observed as variations in subcellular distribution of the protein.

Cell-cycle dependance of observed single-cell varations in RNA and/or protein expression as observed in an additional assay for characterizing single-cell varations.
The custom data section contains information about experiments that were carried out by researchers in the Cell Atlas independent of the general workflow in the project. This includes but is not limited to colocalization experiments with known organelle markers or stainings of proteins in the cell cycle marker cell line U-2 OS FUCCI (Fluorescence Ubiquitination Cell Cycle Indicator). Example images as well as a detailed description of the respective assay are provided. Different organelle probes are displayed as different channels in the multicolor images. By using the "toggle channels"-buttons, the different channels can be turned on and off. To change which images to compare, use the checkboxes next to the images at the bottom. Three images can be compared at a time. All images are clickable for an enlarged view. The selected image will appear in large size and miniature images with all other staining results for this gene will be listed at the top left of the image.

RNA EXPRESSION OVERVIEWi
Overview of RNA expression levels in different cell lines analyzed in the Human Protein Atlas. The RNA-sequencing results generated in the HPA are reported as normalized transcript per million (nTPM) values. In the Human Protein Atlas a nTPM value of 1.0 is defined as a threshold for expression of the corresponding protein. The cell lines are divided into color-coded groups according to their origin in the human body. By clicking the toolbars in the top right corner it is possible to sort the cell lines in the chart by different criteria: the organ and the origin that the cell line was obtained from, the category of the cell line according to cellosaurus, alphabetically or by descending RNA expression. Detailed information about a specific cell line can be accessed by hovering over the corresponding bar in the chart.
