RNA cell categoryi
The cell lines in the Human Protein Atlas have been analyzed by RNA-seq to estimate the transcript abundance of each protein-coding gene. The RNA-seq data was then used to classify all genes according to their cell line-specific expression into one of six different categories, defined based on the total set of all TPM values in all analyzed cell lines.
Protein evidence scores are generated from several independent sources and are classified as evidence at i) protein level, ii) transcript level, iii) no evidence, or iv) not available.
Evidence at protein level
Main locationi
The main location is characterized by presence in all tested cell lines and/or increased intensity compared to other locations. It is highlighted in the illustration to the right. 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.

DATA RELIABILITY
Reliability scorei
A reliability score is set for all genes and indicates the level of reliability of the analyzed protein expression pattern based on available protein/RNA/gene characterization data. The reliability of the annotated protein expression data is also scored depending on similarity in immunostaining patterns and consistency with available experimental gene/protein characterization data in the UniProtKB/Swiss-Prot database.
Below is an overview of RNA expression data generated in the HPA project. The analyzed cell lines are divided into 12 color-coded groups according to the organ they were obtained from. 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. The RNA-sequencing results generated in the HPA are reported as number of Transcripts per Kilobase Million (TPM). In the Human Protein Atlas a TPM value of 1.0 is defined as a treshhold for expression of the corresponding protein.

HUMAN CELLSi
The "human cells" section gives an overview about the subcellular location of the protein of interest obtained by indirect immunofluorescence microscopy, an antibody-based protein-visualization technique. The immunofluorescent analysis is carried out in three different cell lines, one of them always being U-2 OS. A selection of immunofluorescent images is displayed below. Three different organelle probes are displayed as different channels in the multicolor images - nucleus stained in blue, microtubules in red and ER in yellow. The antibody staining targeting the protein of interest is shown in green. By using the toggle channel buttons, the different channels can be turned on and off. For the selection of the 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. The selected miniature image has an orange overlay. For cell structure reference, visit the cell dictionary.

Toggle channelsi
Three different organelle probes are displayed as different channels in the multicolor images - nucleus stained in blue, microtubules in red and ER in yellow. The antibody staining targeting the protein of interest is shown in green. By using the "toggle channels"-buttons, the different channels can be turned on and off. 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.

Location(s) annotated in the corresponding cell line.
Single-cell variationi
As the images in the Cell Atlas provide single cell resolution, variations in protein expression patterns from cell to cell can be observed. A single-cell variation can either be observed in the intensity of the immunofluorescent signal or in the spatial distribution pattern of the protein. This column contains information about whether and for which of the annotated locations a single-cell variation pattern was manually annotated.
Cell cycle dependent variationi
A likely cause for single-cell variation in the immunofluorescent images is cell cycle dependency. This column contains information about whether the manually observed cell-to-cell variation pattern correlates with cell cycle progression.
Gene information from Ensembl and Entrez, as well as links to available gene identifiers are displayed here. Information was retrieved from Ensembl if not indicated otherwise.

Description
Platelet derived growth factor subunit A (HGNC Symbol)
Entrez gene summary
This gene encodes a member of the protein family comprised of both platelet-derived growth factors (PDGF) and vascular endothelial growth factors (VEGF). The encoded preproprotein is proteolytically processed to generate platelet-derived growth factor subunit A, which can homodimerize, or alternatively, heterodimerize with the related platelet-derived growth factor subunit B. These proteins bind and activate PDGF receptor tyrosine kinases, which play a role in a wide range of developmental processes. Alternative splicing results in multiple transcript variants.

The protein browser displays the antigen location on the target protein(s) and the features of the target protein. The tabs at the top of the protein view section can be used to switch between the different splice variants to which an antigen has been mapped.
At the top of the view, the position of the antigen (identified by the corresponding HPA identifier) is shown as a green bar. A yellow triangle on the bar indicates a <100% sequence identity to the protein target.
Under the antigens, the maximum percent sequence identity of the protein to all other proteins from other human genes is displayed, using a sliding window of 10 aa residues (HsID 10) or 50 aa residues (HsID 50). The region with the lowest possible identity is always selected for antigen design, with a maximum identity of 60% allowed for designing a single-target antigen (read more).
The curve in blue displays the predicted antigenicity i.e. the tendency for different regions of the protein to generate an immune response, with peak regions being predicted to be more antigenic.The curve shows average values based on a sliding window approach using an in-house propensity scale. (read more).
If a signal peptide is predicted by a majority of the signal peptide predictors SPOCTOPUS, SignalP 4.0, and Phobius (turquoise) and/or transmembrane regions (orange) are predicted by MDM, these are displayed.
Low complexity regions are shown in yellow and InterPro regions in green. Common (purple) and unique (grey) regions between different splice variants of the gene are also displayed (read more), and at the bottom of the protein view is the protein scale.
