RNA category is based on mRNA expression levels in the analyzed samples (RNA assay description). The categories include: tissue enriched, group enriched, tissue enhanced, expressed in all, mixed and not detected. RNA category is calculated separately for data imported from The Genotype-Tissue Expression project (GTEX), FANTOM5 Consortium (FANTOM5) and internally generated Human Protein Atlas (HPA) data.
Protein evidence scores are generated from several independent sources and are classified as evidence at i) protein level, ii) transcript level, iii) no evidence, or iv) not available.
Evidence at protein level
Protein expressioni
A summary of the overall protein expression pattern across the analyzed normal tissues. The summary is based on knowledge-based annotation.
"Estimation of protein expression could not be performed. View primary data." is shown for genes analyzed with a knowledge-based approach where available RNA-seq and gene/protein characterization data has been evaluated as not sufficient in combination with immunohistochemistry data to yield a reliable estimation of the protein expression profile.
Nuclear and cytoplasmic expression in proliferating cells.

Data reliability descriptioni
Standardized explanatory sentences with additional information required for full understanding of the knowledge-based expression profile.
Antibody staining consistent with RNA expression data.
Reliability scorei
Reliability score (score description), divided into Enhanced, Supported, Approved, or Uncertain, is evaluated in normal tissues and based on consistency between antibody staining pattern, available RNA-Seq and gene/protein characterization data, as well as similarity between independent antibodies targeting the same protein.
Below is an overview of RNA and protein expression data generated in the Human Protein Atlas project. Analyzed tissues are divided into color-coded groups according to which functional features they have in common. For each group, a list of included tissues is accessed by clicking on group name, group symbol, RNA bar, or protein bar. Subsequent selection of a particular tissue in this list links to the image data page.
Images of selected tissues give a visual summary of the protein expression profile furthest to the right.
The gray human body provides links to a histology dictionary when clicking on any part of the figure.
RNA expression (TPM)i
RNA-seq results generated in HPA are reported as number of transcripts per million (TPM). Each bar represents the highest expression score found in a particular group of tissues. The assay is described more in detail in Assays & Annotation.
Protein expression (score)i
Each bar represents the highest expression score found in a particular group of tissues. Protein expression scores are based on a best estimate of the "true" protein expression from a knowledge-based annotation, described more in detail under Assays & annotation. For genes where more than one antibody has been used, a collective score is set displaying the estimated true protein expression.
Protein expression data is shown for each of the 44 tissues. Color-coding is based on tissue groups, each consisting of tissues with functional features in common. Mouse-over function shows protein score for analyzed cell types in a selected tissue. To access image data click on tissue name or bar. Annotation of protein expression is described in detail in Assays & annotation.
For genes with available protein data for which a knowledge-based annotation gave inconclusive results, no protein expression data is displayed in the protein expression data overview. However, all immunohistochemical images are still available and the annotation data can be found under Primary data.

Description
Cyclin dependent kinase 1 (HGNC Symbol)
Entrez gene summary
The protein encoded by this gene is a member of the Ser/Thr protein kinase family. This protein is a catalytic subunit of the highly conserved protein kinase complex known as M-phase promoting factor (MPF), which is essential for G1/S and G2/M phase transitions of eukaryotic cell cycle. Mitotic cyclins stably associate with this protein and function as regulatory subunits. The kinase activity of this protein is controlled by cyclin accumulation and destruction through the cell cycle. The phosphorylation and dephosphorylation of this protein also play important regulatory roles in cell cycle control. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Mar 2009]
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). The region with the lowest possible identity is always selected for antigen design, with a maximum identity of 60% allowed for designing a single-target antigen (read more).
The curve in blue displays the predicted antigenicity i.e. the tendency for different regions of the protein to generate an immune response, with peak regions being predicted to be more antigenic.The curve shows average values based on a sliding window approach using an in-house propensity scale. (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.
