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.

2 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.

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.
