Single cell type - APOM - 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.	APOM
Gene descriptionⁱ Full gene name according to HGNC.	Apolipoprotein M
Protein classⁱ Assigned HPA protein class(es) for the encoded protein(s). Read more	Plasma proteins
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,Secreted
Number of transcriptsⁱ Number of protein-coding transcripts from the gene as defined by Ensembl.	3

HUMAN PROTEIN ATLAS INFORMATIONⁱ Summary of RNA expression and protein localization based on data generated within the Human Protein Atlas project.
Single cell type expression clusterⁱ The RNA data was used to cluster genes according to their expression across single cell types. Clusters contain genes that have similar expression patterns, and each cluster has been manually annotated to describe common features in terms of function and specificity. Read more	Proximal tubular cells - Tubular reabsorption (mainly)
Single cell type specificityⁱ The RNA specificity category is based on mRNA expression levels in the analyzed cell types based on scRNA-seq data from normal tissues. The categories include: cell type enriched, group enriched, cell type enhanced, low cell type specificity and not detected. Read more	Group enriched (Proximal tubular cells, Hepatocytes)
Immune cell specificityⁱ The RNA specificity category is based on mRNA expression levels in the analyzed samples based on data from HPA. The categories include: cell type enriched, group enriched, cell type enhanced, low cell type specificity and not detected. Read more	Immune cell enhanced (basophil)
Immune cell distributionⁱ The RNA distribution category is based on mRNA expression levels in the analyzed samples based on data from HPA. The categories include: detected in all, detected in many, detected in some, detected in single and not detected. Read more	Detected in some
Cell line specificityⁱ RNA specificity category based on RNA sequencing data from all cell lines in the Human Protein Atlas. Genes are classified into six different categories (enriched, group enriched, enhanced, low specificity and not detected) according to their RNA expression levels across the panel of cell lines. Read more	Cell line enriched (Hep G2)
Cell line distributionⁱ RNA distribution category based on RNA sequencing data from all cell lines in the Human Protein Atlas. Genes are classified into five different categories (detected in all, detected in many, detected in some, detected in single and not detected) according to their pattern of detected RNA expression across the panel of cell lines. Read more	Detected in some
Protein evidenceⁱ Evidence score for genes based on UniProt protein existence (UniProt evidence); a Human Protein Atlas antibody- or RNA based score (HPA evidence); and evidence based on PeptideAtlas (MS evidence). The avaliable scores are evidence at protein level, evidence at transcript level, no evidence, or not avaliable. Read more	Evidence at protein level
Extracellular locationⁱ A possible secretion of the protein was predicted based on N-terminal signal sequence (signal peptide) predictions and transmembrane region predictions, and subsequently annotated for its local or systemic secretion based on literature, function, and protein and RNA expression data. Read more	Protein predicted to be secreted

SINGLE CELL TISSUESⁱ Single cell RNA levels of annotated cell type clusters are shown separately for each analyzed tissue. For easier navigation across tissues, use the above Single cell tissue overview, where each tissue name and UMAP plot is clickable and redirects to the selected tissue, alternatively the grey browser on the left side of the window. Barchart shows nTPM levels in each annotated cluster of single cells. To the left, a UMAP plot illustrates the RNA expression profile. The tissue name and plots are clickable and redirect to a more detailed interactive page. Color-coding is based on cell type groups, each consisting of cell types with functional features in common. Please note that the same cell type may be found in several clusters.
