4 GO annotations of cellular component
Name | Definition |
---|---|
cytoplasm | The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
cytosol | The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes. |
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. |
ubiquitin ligase complex | A protein complex that includes a ubiquitin-protein ligase and enables ubiquitin protein ligase activity. The complex also contains other proteins that may confer substrate specificity on the complex. |
3 GO annotations of molecular function
Name | Definition |
---|---|
ubiquitin conjugating enzyme binding | Binding to a ubiquitin conjugating enzyme, any of the E2 proteins. |
ubiquitin protein ligase activity | Catalysis of the transfer of ubiquitin to a substrate protein via the reaction X-ubiquitin + S -> X + S-ubiquitin, where X is either an E2 or E3 enzyme, the X-ubiquitin linkage is a thioester bond, and the S-ubiquitin linkage is an amide bond |
zinc ion binding | Binding to a zinc ion (Zn). |
9 GO annotations of biological process
Name | Definition |
---|---|
endoplasmic reticulum organization | A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of the endoplasmic reticulum. |
oogenesis | The complete process of formation and maturation of an ovum or female gamete from a primordial female germ cell. Examples of this process are found in Mus musculus and Drosophila melanogaster. |
positive regulation of neurogenesis | Any process that activates or increases the frequency, rate or extent of neurogenesis, the generation of cells within the nervous system. |
positive regulation of proteasomal protein catabolic process | Any process that activates or increases the frequency, rate or extent of proteasomal protein catabolic process. |
positive regulation of proteasomal ubiquitin-dependent protein catabolic process | Any process that activates or increases the frequency, rate or extent of the breakdown of a protein or peptide by hydrolysis of its peptide bonds, initiated by the covalent attachment of ubiquitin, and mediated by the proteasome. |
protein monoubiquitination | Addition of a single ubiquitin group to a protein. |
protein polyubiquitination | Addition of multiple ubiquitin groups to a protein, forming a ubiquitin chain. |
protein ubiquitination | The process in which one or more ubiquitin groups are added to a protein. |
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. |
