Subcellular - PARS2 - The Human Protein Atlas

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.	PARS2
Gene descriptionⁱ Full gene name according to HGNC.	Prolyl-tRNA synthetase 2, mitochondrial
Protein classⁱ Assigned HPA protein class(es) for the encoded protein(s). Read more	Disease related genes Enzymes Human disease related genes 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. Read more	Intracellular
Number of transcriptsⁱ Number of protein-coding transcripts from the gene as defined by Ensembl.	1

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.

Single-cell variationⁱ Single-cell variations of protein expression or distribution observed within single images in human cells. Variation in protein expression levels can be observed as varaiations in the intensity of the immunofluorescent signal, while spatial variations can be observed asvariations in subcellular distribution of the protein. Read more	Single-cell variation in protein expression observed.
Cell cycle dependencyⁱ Cell-cycle dependance of single-cell varations in RNA and/or protein expression as observed in an additional assay for characterizing single-cell varations. "NA" indicates a lack of such data. Read more	Variation in protein and transcript expression do not correlate to the cell-cycle.
Reliability scoreⁱ Overall gene reliability score for the subcellular location(s) of the encoded protein(s). 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.

	Toggle channelsⁱ 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.
