Descriptions
Ubiquitin conjugating enzyme E2 S (UBE2S) is a protein that plays a key role in accepting ubiquitin from the E1 complex and catalyzing its covalent attachment to other proteins. Dimerization regulates UBE2S by preventing autoubiquitination, thus stabilizing the protein and allowing it to inhibit premature ubiquitin chain elongation during the cell cycle. The autoinhibition is mediated by blocking the ubiquitin-binding sites in UBC domain, which are essential for its E2 activity. The C-helix of UBE2S engages the APC/C for chain elongation, blocking the promotion of UBE2S autoinhibition through dimerization achieved by C-helix.

4 GO annotations of cellular component
| Name | Definition |
|---|---|
| anaphase-promoting complex | A ubiquitin ligase complex that degrades mitotic cyclins and anaphase inhibitory protein, thereby triggering sister chromatid separation and exit from mitosis. Substrate recognition by APC occurs through degradation signals, the most common of which is termed the Dbox degradation motif, originally discovered in cyclin B. |
| cytosol | The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes. |
| endoplasmic reticulum | The irregular network of unit membranes, visible only by electron microscopy, that occurs in the cytoplasm of many eukaryotic cells. The membranes form a complex meshwork of tubular channels, which are often expanded into slitlike cavities called cisternae. The ER takes two forms, rough (or granular), with ribosomes adhering to the outer surface, and smooth (with no ribosomes attached). |
| nucleus | A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent. |
2 GO annotations of molecular function
| Name | Definition |
|---|---|
| ATP binding | Binding to ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator. |
| ubiquitin conjugating enzyme activity | Isoenergetic transfer of ubiquitin from one protein to another via the reaction X-ubiquitin + Y -> Y-ubiquitin + X, where both the X-ubiquitin and Y-ubiquitin linkages are thioester bonds between the C-terminal glycine of ubiquitin and a sulfhydryl side group of a cysteine residue. |
8 GO annotations of biological process
| Name | Definition |
|---|---|
| anaphase-promoting complex-dependent catabolic process | The chemical reactions and pathways resulting in the breakdown of a protein or peptide by hydrolysis of its peptide bonds, initiated by the covalent attachment of ubiquitin, with ubiquitin-protein ligation catalyzed by the anaphase-promoting complex, and mediated by the proteasome. |
| cell division | The process resulting in division and partitioning of components of a cell to form more cells; may or may not be accompanied by the physical separation of a cell into distinct, individually membrane-bounded daughter cells. |
| exit from mitosis | The cell cycle transition where a cell leaves M phase and enters a new G1 phase. M phase is the part of the mitotic cell cycle during which mitosis and cytokinesis take place. |
| free ubiquitin chain polymerization | The process of creating free ubiquitin chains, compounds composed of a large number of ubiquitin monomers. These chains are not conjugated to a protein. |
| positive regulation of ubiquitin protein ligase activity | Any process that activates or increases the frequency, rate or extent of ubiquitin protein ligase activity. |
| protein K11-linked ubiquitination | A protein ubiquitination process in which ubiquitin monomers are attached to a protein, and then ubiquitin polymers are formed by linkages between lysine residues at position 11 of the ubiquitin monomers. K11-linked polyubiquitination targets the substrate protein for degradation. The anaphase-promoting complex promotes the degradation of mitotic regulators by assembling K11-linked polyubiquitin chains. |
| protein polyubiquitination | Addition of multiple ubiquitin groups to a protein, forming a ubiquitin chain. |
| ubiquitin-dependent protein catabolic process | The chemical reactions and pathways resulting in the breakdown of a protein or peptide by hydrolysis of its peptide bonds, initiated by the covalent attachment of a ubiquitin group, or multiple ubiquitin groups, to the protein. |
