The gene information section lists the gene name (HUGO Gene Nomenclature Committee (HGNC) name if available), any approved gene synonyms, Ensembl gene description, and the Entrez gene summary from the National Center for Biotechnology Information.
The chromosomal and cytoband location of the gene according to Ensembl is reported together with the Ensembl gene identifier and Ensembl database version. The Entrez gene identifier for the gene is also given. If any of the protein products of the gene is linked to a UniProt KB/SWISS-PROT entry, links to the UniProt and the neXtProt databases for these proteins are displayed.
This gene encodes a potent cyclin-dependent kinase inhibitor. The encoded protein binds to and inhibits the activity of cyclin-CDK2 or -CDK4 complexes, and thus functions as a regulator of cell cycle progression at G1. The expression of this gene is tightly controlled by the tumor suppressor protein p53, through which this protein mediates the p53-dependent cell cycle G1 phase arrest in response to a variety of stress stimuli. This protein can interact with proliferating cell nuclear antigen (PCNA), a DNA polymerase accessory factor, and plays a regulatory role in S phase DNA replication and DNA damage repair. This protein was reported to be specifically cleaved by CASP3-like caspases, which thus leads to a dramatic activation of CDK2, and may be instrumental in the execution of apoptosis following caspase activation. Multiple alternatively spliced variants have been found for this gene. [provided by RefSeq, Nov 2010]
The protein view displays protein features. The tabs at the top of the protein view section can be used to switch between the different splice variants encoded by this gene. The mouse over function displays additional data for the features in the protein view.
At the top of the protein view, the maximum percent sequence identity of the protein to all other proteins from other human genes is shown, 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.
Common (purple) and unique (grey) regions between alternative processed transcripts from the same gene are also displayed (read more), and at the bottom of the protein view is the protein scale.
The protein information section displays the alternative protein-coding transcripts (splice variants) encoded by this gene, according to the Ensembl database.
The ENSP identifier links to the Ensembl website for that protein, and the ENST identifier links to the Ensembl website for that transcript. The data in the UniProt column can be expanded to show links to all matching UniProt identifiers for this protein.
The protein classes to which this protein has been assigned 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 predicted transmembrane region(s) (according to MDM) are also reported.
