Descriptions
E3 ubiquitin-protein ligase ARIH2 catalyzes ubiquitination of target proteins together with ubiquitin-conjugating enzyme E2 UBE2L3 and acts as an atypical E3 ubiquitin-protein ligase by working together with cullin-5-RING ubiquitin ligase complex and initiating ubiquitination of ECS substrates. ARIH2 is autoinhibited by the ariadne domain, which masks the second RING-type zinc finger that contains the active site and inhibits the E3 activity. Inhibition is relieved upon binding to neddylated cullin-RING ubiquitin ligase complexes, which activate the E3 ligase activity.

3 GO annotations of cellular component
| Name | Definition |
|---|---|
| cytoplasm | The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
| 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). |
3 GO annotations of biological process
| Name | Definition |
|---|---|
| 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 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. |
