Copper Metabolism Domain Containing 1 (COMMD1) Human Recombinant Protein

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

Cellular Component: Cul2-RING ubiquitin ligase complex; nucleoplasm; recycling endosome; cytoplasm; early endosome; cytoplasmic membrane-bound vesicle; endosome membrane; nucleus

Molecular Function: identical protein binding; phosphatidylinositol-4,5-bisphosphate binding; protein binding; copper ion binding; protein homodimerization activity; phosphatidylinositol-3,4,5-triphosphate binding; phosphatidylinositol-3,4-bisphosphate binding

Biological Process: Golgi to plasma membrane transport; protein transport; transcription, DNA-dependent; positive regulation of protein ubiquitination; inhibition of NF-kappaB transcription factor; regulation of proteasomal ubiquitin-dependent protein catabolic process; plasma membrane to endosome transport; copper ion homeostasis
