COMMD1 Antibody – Rabbit Polyclonal

COMMD1: 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.

Protein type: Inhibitor

Chromosomal Location of Human Ortholog: 2p15
