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.

CD44
Gene descriptioni

Full gene name according to HGNC.

CD44 molecule (Indian blood group)
Protein classi

Assigned HPA protein class(es) for the encoded protein(s).

Blood group antigen proteins
Cancer-related genes
CD markers
FDA approved drug targets
Plasma proteins
Transporters
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.

Secreted, Membrane, Intracellular
Number of transcriptsi

Number of protein-coding transcripts from the gene as defined by Ensembl.

HUMAN PROTEIN ATLAS INFORMATIONi

Summary of RNA expression analysis and annotation data generated within the Human Protein Atlas project.

Tissue specificity HPA (aggregated)i

The aggregated tissue specificity category corresponds to the combined unique specificity categories of all individual isoforms for the gene, based on HPA RNA-seq data

Read more
Enhanced, enriched, low specificity
Tissue specificity GTEx (aggregated)i

The aggregated tissue specificity category corresponds to the combined unique specificity categories of all individual isoforms for the gene, based on GTEx RNA-seq data.

Read more
Enhanced, enriched, low specificity
Tissue expression
cluster (RNA)i

The RNA data was used to cluster genes according to their expression across tissues. 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.

Skin - Keratinization (mainly)
Expression category (HPA)i

The expression category reflects the overall expression pattern for the gene based on expression profiles for all individual isoforms.

Many expressed
Expression category (GTEx)i

The expression category reflects the overall expression pattern for the gene based on expression profiles for all individual isoforms.

Read more
Many expressed
Tissue specificity (RNA)i

The RNA specificity category is based on mRNA expression levels in the consensus dataset which is calculated from the RNA expression levels in samples from HPA and GTEX. The categories include: tissue enriched, group enriched, tissue enhanced, low tissue specificity and not detected.

Low tissue specificity

PROTEIN INFORMATIONi

The protein information section displays alternative protein-coding transcripts (splice variants) encoded by this gene according to the Ensembl database.

The Splice variant identifier links to the Ensembl website protein summary for the selected splice variant. The data in the Swissprot and TrEMBL columns links to corresponding pages in the UniProt database.

The protein classes assigned to this protein are shown if expanding the data in the protein class column. Parent protein classes are in bold font and subclasses are listed under the parent class.

The length of the protein (amino acid residues according to Ensembl), molecular mass (kDalton), predicted signal peptide and number of predicted transmembrane region(s) according to in-house majority decision methods based on sets of predictors are also reported.
