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.
Deoxynucleotidyltransferase terminal interacting protein 2
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.
Number of protein-coding transcripts from the gene as defined by Ensembl.

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.
Main subcellular location(s) and reliability score(s) for the encoded protein(s) in human cells. The main location(s) may be characterized by presence in all tested cell lines and/or ihigher staining intensity compared to the potential additional location(s). If available, links to overrepresentation analyses in Reactome, a free, open-source, curated and peer reviewed biological pathway database, are provided.

SINGLE CELL VARIATIONi
Summary of single cell variations on RNA and protein level based on data generated within the Human Protein Atlas project.
Single-cell variationi
Single-cell variations of protein expression or distribution observed within single images in human cells. Variation in protein expression levels can be observed as varaiations in the intensity of the immunofluorescent signal, while spatial variations can be observed asvariations in subcellular distribution of the protein.
Single-cell variation in protein expression observed.
Cell cycle dependencyi
Cell-cycle dependance of single-cell varations in RNA and/or protein expression as observed in an additional assay for characterizing single-cell varations. "NA" indicates a lack of such data.
The protein is localized to mitotic structures and is thus associated with the cell-cycle. Variation in transcript expression is not correlated to the cell cycle across interphase.
DATA RELIABILITYi
Overall reliability score for the subcellular location(s) of the protein(s) in human cells, and summary of the antibodies used for immunostainings.
Overall gene reliability score for the subcellular location(s) of the encoded protein(s). A reliability score is set for all genes and indicates the level of reliability of the analyzed protein expression pattern based on available protein/RNA/gene characterization data. The reliability of the annotated protein expression data is also scored depending on similarity in immunostaining patterns and consistency with available experimental gene/protein characterization data in the UniProtKB/Swiss-Prot database.
Overview of RNA expression levels in different cell lines analyzed in the Human Protein Atlas. The RNA-sequencing results generated in the HPA are reported as normalized NX values. In the Human Protein Atlas a NX value of 1.0 is defined as a threshhold for expression of the corresponding protein. The cell lines are divided into color-coded groups according to their origin in the human body. By clicking the toolbars in the top right corner it is possible to sort the cell lines in the chart by different criteria: the organ and the origin that the cell line was obtained from, the category of the cell line according to cellosaurus, alphabetically or by descending RNA expression. Detailed information about a specific cell line can be accessed by hovering over the corresponding bar in the chart.

Protein expression across cell cyclei
Assay for determining protein expression level and cell cycle phase in single cells by indirect immunofluorescence microscopy in the U-2 OS FUCCI cell line.
