The cancer tissue page shows antibody staining in 20 different cancers. The assay and annotation is described here.
This page starts with information about the protein evidence and, when applicable, also protein class. Below the summary, a selection of four standard cancer tissue samples is displayed as representative of the overall staining pattern. From left: colorectal cancer, breast cancer, prostate cancer and lung cancer. An additional 5th image can be added as a complement.

Evidence at protein level
The cancer tissue summary page shows antibody staining in 20 different cancers. The assay and annotation is described here.
For each cancer, the fraction of samples with antibody staining/protein expression level high, medium, low, or not detected are provided by the blue-scale color-coding (as described by the color-coding scale in the box to the right). The length of the bar represents the number of patient samples analyzed (max=12 patients). The images and annotations can be accessed by clicking on the cancer name or protein expression bar. If more than one antibody is analyzed, the tabs at the top of the staining summary section can be used to toggle between the different antibodies. The tooltip function displays additional data for the features in the staining summary view.
Next to the cancer staining data, the protein expression data of normal tissues or specific cell types corresponding to each cancer are shown and protein expression levels are indicated by the blue-scale color coding.
At the bottom of the page, a summary of the overall protein expression pattern across the analyzed cancer tissues as well as information about literature conformity are presented.
A few cases of lymphoma displayed moderate to strong nuclear and cytoplasmic immunoreactivity. Remaining cancer tissues were generally negative.
Gene information from Ensembl and Entrez, as well as links to available gene identifiers are displayed here. Information was retrieved from Ensembl if not indicated otherwise.
IRF4 (HGNC Symbol)
Interferon regulatory factor 4 (HGNC Symbol)
Entrez gene summary
The protein encoded by this gene belongs to the IRF (interferon regulatory factor) family of transcription factors, characterized by an unique tryptophan pentad repeat DNA-binding domain. The IRFs are important in the regulation of interferons in response to infection by virus, and in the regulation of interferon-inducible genes. This family member is lymphocyte specific and negatively regulates Toll-like-receptor (TLR) signaling that is central to the activation of innate and adaptive immune systems. A chromosomal translocation involving this gene and the IgH locus, t(6;14)(p25;q32), may be a cause of multiple myeloma. Alternatively spliced transcript variants have been found for this gene.

The protein browser displays the antigen location on the target protein(s) and the features of the target protein. The tabs at the top of the protein view section can be used to switch between the different splice variants to which an antigen has been mapped.
At the top of the view, the position of the antigen (identified by the corresponding HPA identifier) is shown as a green bar. A yellow triangle on the bar indicates a <100% sequence identity to the protein target.
Under the antigens, the maximum percent sequence identity of the protein to all other proteins from other human genes is displayed, using a sliding window of 10 aa residues (HsID 10) or 50 aa residues (HsID 50) (read more).
If a signal peptide is predicted by a majority of the signal peptide predictors SPOCTOPUS, SignalP 4.0, and Phobius (turquoise) and/or transmembrane regions (orange) are predicted by MDM, these are displayed.
Low complexity regions are shown in yellow and InterPro regions in green. Common (purple) and unique (grey) regions between different splice variants of the gene are also displayed (read more), and at the bottom of the protein view is the protein scale.
The protein information section displays alternative protein-coding transcripts (splice variants) encoded by this gene according to the Ensembl database.
The ENSP identifier links to the Ensembl website protein summary, while the ENST identifier links to the Ensembl website transcript summary for the selected splice variant. The data in the UniProt column can be expanded to show links to all matching UniProt identifiers for this protein.
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 Gene Ontology terms assigned to this protein are listed if expanding the Gene ontology column. The length of the protein (amino acid residues according to Ensembl), molecular mass (kDalton), predicted signal peptide (according to a majority of the signal peptide predictors SPOCTOPUS, SignalP 4.0, and Phobius) and the number of predicted transmembrane region(s) (according to MDM) are also reported.
