Descriptions
The N-terminal region of SUMO1 functions as an autoinhibition domain by blocking its binding to the phosphorylated SIMs of PML and Daxx. This autoinhibition is relieved by zinc, which stabilizes the complex between SUMO1 and a phospho-mimetic form of the SIM of PML, suggesting a paralog specific function of SUMO1 in regulating SUMO1-SIM interactions required for PML-NB formation and function.

3 GO annotations of cellular component
| Name | Definition |
|---|---|
| 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. |
| PML body | A class of nuclear body; they react against SP100 auto-antibodies (PML, promyelocytic leukemia); cells typically contain 10-30 PML bodies per nucleus; alterations in the localization of PML bodies occurs after viral infection. |
| septin ring | A tight ring-shaped structure that forms in the division plane at the site of cytokinesis; composed of members of the conserved family of filament-forming proteins called septins as well as septin-associated proteins. This type of septin structure is observed at the bud neck of budding fungal cells, at the site of cell division in animal cells, at the junction between the mother cell and a pseudohyphal projection, and also within hyphae of filamentous fungi at sites where a septum will form. |
2 GO annotations of molecular function
| Name | Definition |
|---|---|
| protein tag activity | A molecular function exhibited by a protein that is covalently attached (AKA tagged or conjugated) to another protein where it acts as a marker, recognized by the cellular apparatus to target the tagged protein for some cellular process such as modification, sequestration, transport or degradation. |
| ubiquitin-like protein ligase binding | Binding to a ubiquitin-like protein ligase, such as ubiquitin-ligase. |
1 GO annotations of biological process
| Name | Definition |
|---|---|
| protein sumoylation | The process in which a SUMO protein (small ubiquitin-related modifier) is conjugated to a target protein via an isopeptide bond between the carboxy-terminus of SUMO with an epsilon-amino group of a lysine residue of the target protein. |
