Protein Structure
UniProt Annotation
Function Promotes ubiquitination of NF-kappa-B subunit RELA and its subsequent proteasomal degradation. Down-regulates NF-kappa-B activity. Down-regulates SOD1 activity by interfering with its homodimerization. Plays a role in copper ion homeostasis. Can bind one copper ion per monomer. May function to facilitate biliary copper excretion within hepatocytes. {ECO:0000269PubMed:14685266, ECO:0000269PubMed:15799966, ECO:0000269PubMed:16573520, ECO:0000269PubMed:17183367, ECO:0000269PubMed:17309234, ECO:0000269PubMed:20048074, ECO:0000269PubMed:20595380}.
Subcellular Localization Nucleus. Cytoplasm. Note=Shuttles between nucleus and cytosol. Detected in perinuclear foci that may be aggresomes containing misfolded, ubiquitinated proteins.
Disease Associations
Tissue Specificity Ubiquitous. Highest expression in the liver, with lower expression in brain, lung, placenta, pancreas, small intestine, heart, skeletal muscle, kidney and placenta. {ECO:0000269PubMed:11809725, ECO:0000269PubMed:15799966, ECO:0000269PubMed:16573520}.
