Single cell type - CKLF-CMTM1 - 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.	CKLF-CMTM1
Gene descriptionⁱ Full gene name according to HGNC.	CKLF-CMTM1 readthrough
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.	Membrane
Number of transcriptsⁱ Number of protein-coding transcripts from the gene as defined by Ensembl.	5

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.	Late spermatids - Spermiogenesis: Maturation (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.	Cell type enhanced (Late spermatids, Hepatic stellate cells, Late primary spermatocytes, Early spermatids, Epicardial cells)
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.	0.97
Brain cluster specificityⁱ The RNA specificity category is based on mRNA expression levels in the analyzed cell cluster types based on snRNA-seq data from brain samples. The categories include: cell type enriched, group enriched, cell type enhanced, low cell type specificity and not detected. "cell type" refer to one of the 34 cluster names used to summarize the 2.5 million cells included in the brain cell representation.	Not available
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.	Low immune cell specificity
Protein evidenceⁱ Evidence score for genes based on UniProt protein existence (UniProt evidence); neXtProt protein existence (neXtProt evidence);and a Human Protein Atlas antibody- or RNA based score (HPA evidence). The avaliable scores are evidence at protein level, evidence at transcript level, no evidence, or not avaliable.	Evidence at transcript level
