Cell line - COL8A1 - 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.	COL8A1
Gene descriptionⁱ Full gene name according to HGNC.	Collagen type VIII alpha 1 chain
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	Secreted
Number of transcriptsⁱ Number of protein-coding transcripts from the gene as defined by Ensembl.	5

HUMAN PROTEIN ATLAS INFORMATIONⁱ Summary of RNA expression based on cell line data from the DepMap portal and cell line data generated within the Human Protein Atlas project.
Cell line expression clusterⁱ The RNA data was used to cluster genes according to their expression across cell lines. 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	Connective tissue cells - ECM organization (mainly)
Cell line specificityⁱ RNA specificity category based on RNA sequencing data from cancer cell lines in the Human Protein Atlas grouped according to type of cancer. 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	Cancer enhanced (Brain cancer, Kidney cancer, Thyroid cancer)
Tau specificity scoreⁱ Tau specificity score is a numerical indicator of the specificity of the gene expression across cells or tissues. The value ranges from 0 and 1, where 0 indicates identical expression across all cells/tissue types, while 1 indicates expression in a single cell/tissue type. Read more	0.57
Cell line distributionⁱ RNA distribution category based on RNA sequencing data from cancer cell lines in the Human Protein Atlas grouped according to type of cancer. 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 many
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

CELL LINESⁱ RNA expression data as normalized transcript per million (nTPM) values of cancer cell lines.The analyzed cell lines are grouped according to cancer type. Detailed information about the groups is revealed by hovering over the corresponding bar in the chart. More information and cell line data can be found in the Cell line section. Read more
Cell line categories Alphabetical Expression RNA specificity:Cancer enhanced (Brain cancer, Kidney cancer, Thyroid cancer)
