Protein Structure

|
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}.
